A Beginner's Guide to Programming Languages

Updated on November 4, 2013

How To Choose Which Programming Language to Learn

Since you have chosen to visit a page about programming languages I am going to assume that you already know about the many benefits of learning to code. So, you have already decided that you are interested in the possibility of learning to become a programmer, but you just don't know where to start.

There are literally hundreds of different computer programming languages out there, and it can be quite difficult to pick the one(s) that will be most useful to you if you are a complete beginner and still know very little about each one.

To help you decide which programming language(s) to learn this article will guide you through the different types and explain the process of choosing the right language to meet your goals. It will also include an introduction to many of the most popular languages in use today.

Have a Clear Vision of What You Want to Achieve

If you want to make sure that you pick the right learning path to help you achieve all of your goals then it is obviously important to be as clear as possible in your mind what those goals are. Even if you are a complete beginner and just want to learn to code because you think it may help your career or because you have heard it is a rewarding thing to do, it is still worth thinking about the kind of project you are likely to be interested in getting involved with so that you can learn the right skills.

If you want to make apps then you will take a different path to someone who wants to develop websites, which again is different to someone who would like to develop desktop software, which is different again to industrial software, and so on.

Common Goals for Beginners with Suggested Learning Paths

Making Your Own Apps  
Website Development  
Becoming a Freelancer  
High Flying Career  
It's a good idea to take the time to learn the basic principles of computer science before you do anything else
Choose which platform you want to program for first and choose a language accordingly
Python is a popular choice as a starter language for academics
Learning the ins and outs of CMS like Wordpress is a very good idea if you want work as a freelance programmer
C, C++, Visual Basic, or Java
These are just suggestions, please read the full article and make a properly informed decision of your own.

Most People Start With...

  • HTML, or HyperText Markup Language is the place where most people start. It is used to give structure to most webpages and you can learn to create a basic page in just a few hours!
  • CSS is often learnt together with HTML, and is used on most websites to define layout and styling

Client-Side and Server-Side Languages

'Client Side' and 'Server Side' may sound like difficult technical terms to some, but they just refers to the location where data is processed.

Client side means that the server hosting a web site or app provides the code to a user's device without doing anything with it, this code is then run on that device itself, typically within a browser. For many simple and self-contained applications this can be a great way to make sure that the server's workload is kept down, and to ensure fast performance for the application. A very popular example of a client-side language which is easy to learn is JavaScript.

Server side means that the code is actually run on the server hosting the web site or application, and only the result of running the code is subsequently sent to the user's device. This is an essential requirement for larger applications or functions which need to access information stored in a database, for example. By far the most popular server side language for creating web sites is PHP, which often works together with SQL or mySQL databases.

High and Low Level Languages

Most code written to create software and applications for the general public to use is written in a high level language. This just means that it is closer to the machine's user than to the machine. A low level language is much closer to the actual binary machine code of 1's and 0's which runs on the hardware itself.

Most programming languages are software products, which themselves are written in other languages! Higher level code is usually translated into lower level code, perhaps multiple times, in order to be actually run on the machine.

Object-Oriented Programming Languages

Object-oriented programming (OOP) is the most common 'paradigm' that most software and web developers will work within. Many coders will spend the whole of their career working primarily with OOP and will never need to learn another 'paradigm' in any significant depth.

OOP is a very powerful type of language based on the creation of 'objects' which can be associated with both data fields (lists, variables) and methods (functions). Because it is so effective and so popular it is highly likely that you will start your programming career with OOP.

Some languages are entirely object-oriented (OO), meaning that they treat everything as an object, even down to individual characters; these are called pure OO. But most code you will come across just uses objects as part of the way that they operate

10 of the Most Popular Programming Languages

  1. HTML/CSS: Many people don't consider these to be programming languages, and strictly speaking they are probably right, but this is where most people start and this page is written mainly for beginners so I have included them here in first place. If you want to create a basic static web page then you can do that with HTML/CSS, which is very easy to learn.
  2. JavaScript: JavaScript is a very popular way to add interactive features to web pages and apps. It is one of the easiest languages to learn and can be used for anything from validating form data to developing games, making it a very popular choice for beginners. It is a client-side prototype based language with elements of OOP.
  3. PHP: This is the most popular server-side language and is used mainly for developing dynamic web pages. This means that rather than creating a separate file full of code for every page of a site, you can write a set of rules for accessing and displaying information from a database which can then create pages as and when they are needed.
  4. C++.: Developed to add object-oriented features to the C language,with the addition of classes and other features. C++ is now widely used with a substantial range of applications. Learning C++ also has the advantage of making it easier to pick up both C# and Objective C. All C languages are generally seen as mid-level.
  5. C#: Pronounced C Sharp, this language was created by Microsoft within its .NET framework. If you want to write windows applications, or especially if you want to write code for desktop software, this is essential. It is a general purpose OOP which shares many similarities with the older C language on which it is based, as well as others based on C such as C++.
  6. Objective C: This is the version of C used by Apple operating systems as well as a small number of other applications. If you want to specialise in writing code for Apple products then this is what you will need to learn.
  7. Python: This is a popular high level interpreted language (see below for what interpreted means). It is very popular within the academic and scientific community, but has also been used to create popular websites such as Pinterest. It is relatively easy to learn compared to something like C or its derivatives, but is still very flexible in terms of what you can do with it.
  8. Java: Used by Google as an integral part of the Android operating system, and by independent developers to create android apps (as well as other uses). Java was created with a "write once, run anywhere" (WORA) approach to make it easier for code written on one machine to run on another.
  9. Ruby: This is a popular pure OOP from Japan. People often approach Ruby first through 'Ruby on Rails', an open source application framework for creating apps written in Ruby which is very popular.
  10. Visual Basic: Derived from 'BASIC', which was very popular in the early days of personal computing, Visual Basic (VB) allows for simple programs to be created quickly and easily, whilst also allowing for more complex coding. It was created by Microsoft but older versions are no longer supported and the newest version may not be supported after Windows 8.


Interpreted and Compiled Languages

A compiled language will take the code that you write and turn it into the 1's and 0's of machine readable binary code. When the software is then used, it is this machine code which is actually run. An interpreted language executes the code you write step by step by translating it into machine code as it goes, without needing to 'compile' the code in advance.

In general, compiled languages have improved performance whereas code written in interpreted languages is easier to deploy and modify.

In principle any language can be either interpreted or compiled, as this relates to the method through which the code is executed rather than the syntax and structure of the code itself. In practice, however, many languages are exclusively interpreted or exclusively compiled - although some can be used in either way.

Common Interpreted languages include PHP and Python, whereas the C languages are almost always compiled.

Embeddable Languages

If code is 'embeddable' then it means that you can include small pieces of code within a text document, such as a html webpage. You can use this to add extra functionality to a page with an embeddable language without having to write the whole page in that language. JavaScript, PHP and Python are all embeddable.

Imperative and Declarative Programming

Imperative programming languages specify each step that the computer must take to complete a task, whereas declarative languages tell the computer what it should accomplish but leave some freedom as to which steps to take.

At the lowest level all of the instructions run by a computer are communicated to it as imperative commands, but higher level languages may be thought of as being placed on a continuum between Imperative and Declarative.


Many popular higher level languages are procedural. This means that methods or functions can be called, some of which may be already built into the language, to perform certain actions. In some ways this moves the experience of writing code from away from a purely Imperative paradigm and closer to Declarative, as the desired function may be called without the person who is calling it having to specify all of the steps that the machine should perform to complete that function themselves. The imperative commands are, however, still there under the surface.


A functional language does not have mutable data structures which can change their state throughout the code. They are made up from self-contained functions which depend only on their own inputs. They cannot modify the values in lists, variables and so on, meaning that each function will always have the same result no matter what the rest of the code is doing.

Because functional code relies on mathematical principles it doesn't need to specify the individual steps which the computer must take, and so is classed as a Declarative language.

This kind of code is mainly used in commercial and industrial applications or for academic purposes, rather than in consumer products. Popular functional languages include F# and Haskell.

Any logic based programming language will be declarative.

Data-Oriented Languages

This kind of language is intended purely for storing, searching and manipulating data, often in the form of database tables.

The most popular example of this is SQL, which is used by many websites to create, maintain, optimize and access information from databases stored on servers. Most websites, especially large ones, will store all of their text, as well as images, videos and even structural elements such as categories and tags within databases.

Because it works with data and logical structure, SQL is classed as a declarative language.


Assembly languages are the lowest level of code before you reach machine code itself. They are used to translate the machine code into a form which can be read by humans, and to transmit direct commands to make changes to the state of the machine code.

Very few programmers will ever need to work with assembly during their careers, but a basic understanding of how it works can be very helpful in gaining a more in-depth understanding of what is happening when higher level code is actually run on a machine. It can also be useful if you want to work within embedded electronics, in some areas of hardware development, or in the development of other programming languages.

      Thanks Susi - you've done really well to make your own app, I hope you let me know when its done so I can check it out, I do have an Android phone. I love python myself; never learnt Java personally and it always did look like a tough one to me!

      Excellent hub, Dean! This hub is packed with so much advice and expert knowledge, I have always wanted to learn about other programming languages apart from the ones I know but never got round to it. Right now, I am learning and creating projects in Python and I am learning basic Java for use in creating Android Apps. I am hoping to publish one soon, it was so difficult to code though! Well done, another great hub! Voted interesting, useful and shared.

      Good hub and the summary. I would like to and that in programming career there is also the law of supply and demand. When you are flexible and can learn quickly then you should not have any problems with jobs. It is also important to know several languages, for instance one object oriented and functional.

      Self learning is more difficult, but its definitely possible - the most important thing to remember when you are sitting there trying and failing to follow the logic of an example, or (even more likely) failing to work out why your code doesn't work is that this isn't because you aren't capable of understanding these thing - its because everyone finds it hard (especially at first). Even very experienced programmers often have the same experience, and might sometimes spend a day or more working on just a few lines of code. Of course the good thing is that you can do quite a lot with just a few lines of code! Forums are also an important part of being a programmer - if there is something you can't follow then post a question to a forum and you sure to find people willing to help. You must have learned quite a lot already to get to stuff about classes, so I think it would be a shame for you to give up on it entirely.

      Awesome! If you are an established programmer, what would you say about my giving up self-learning Python after reaching "classes" and a lot of frustration! :-) i never seem to grasp to logical flow of a program. Now I am finishing HTML and CSS from W3schools!

      It can be very time intensive - but remember that once you have one language under your belt learning a second one is much easier.

      Very nice explanation on the basics of computer programming. I tinker with Visual Basic myself, and I wish I had more time to dive more deeply into other languages, but because programming is very time intensive I rarely had any spare moments for it. Great hub!

      Thanks jponiato, that's great - I wish I had learned more BASIC. I had an Acorn Electron way back in the day and my friend showed me a little bit of BASIC when he was making simple game, but I never really learned it properly.

      Very nice and thorough treatment. I started with BASIC on a Commodore C-64 (lol) and been in IT ever since.

      Dean Walsh 

      5 years ago from Birmingham, England

      It definitely is a lot easier to learn more once you have learned one (other than html) because many of the main structures like if/else statements and while loops and so on are basically the same, so you just need to learn a different syntax for writing them rather than learning everything from scratch about how to use them and what they can do - I'd love to learn an assembly language but I'm sure you are right that it is very hard! Thanks for the comment :)

      5 years ago from Japan

      Great Hub. I think that once you learn one, you should have the capacity to learn many, however some are harder than others. I started on BASIC then Pascal and Low level assembly language (very hard)

      You're right, personally I found JavaScript easier than PHP too, but if you want to create a whole website then PHP is the way to go. Thanks for sharing your experience!
