let is useful if you don't want to define a variable and just use it within the scope of the block you're passing to let. Example:

Normally you'd do:

val foo = lookupFoo()
if (foo != null) {
    foo.doThing()
}

It's cleaner to do lookupFoo()?.let { it.doThing() }

No variable needed to be defined
