What is the difference between a var and a val in Scala?

In Scala, a var is a mutable variable, which means its value can be changed after it is initialized. On the other hand, a val is an immutable variable, and its value cannot be changed once it is assigned.

Using val is encouraged in Scala programming as it helps in writing more functional and reliable code by reducing the chance of unintended side effects. On the other hand, var should be used sparingly when mutable state is absolutely necessary.

Understanding the difference between var and val is crucial in Scala programming and can help in writing more concise and predictable code.
