Its not just for growth. All reptiles eventually get to a size where they don't actually grow anymore. People say they grow their whole life, but they get to an age where the growth is insignificant. The scales on reptiles contain vital nutrients to keep that animal in top shape so the shedding is also done in order to replenish those nutrients.

Snakes, and all reptiles shed their skin. When they grow the skin that was on them does no longer fit, so they shed it. The new skin looks much better too.
VeryElite says
Snakes shed when they grow too big for their skin, comparable to the way humans outgrow clothing. Humans shed skin cells too. However, instead of losing skin cells as one continuous and noticeable piece, humans lose numerous, tiny skin cells each day. No one really notices this shedding, as human skin cells are small enough to escape observation.
