apply 

This may be the first time you're seeing the apply function in Kotlin. apply is a scope function in the Kotlin standard library. It executes a block of code within the context of an object. It forms a temporary scope, and in that scope, you can access the object without its name. The common use case for apply is to configure an object. Such calls can be read as "apply the following assignments to the object."
