Mutable and Immutable Variables

In Kotlin, variables can be mutable or immutable. There are instances where a variable’s data will never change throughout the program. In such cases, you have to declare your variable with val. On the other hand, if the data in the variable can change, use var.

Using const variables

const is another Kotlin keyword used to indicate a variable that can’t be changed. The difference between const and val is that const variables are only allowed on top-level, named objects or companion objects. For a variable to be at such high scopes, it means it has to be accessible throughout the whole file and not in the function. Same as the val, any attempt to alter a const variable will result in an error.
