It just runs the code 🙂
So, obj.let { it.action() } if equivalent to obj.action().
In obj?.let { … } the obj is nullable, and it is nun-null so it comes very handy when you need to acces a nullable variable’s value several times when it is non-null.
This is the definition of `let`:
public inline fun <T, R> T.let(block: (T) -> R): R = block(this)
