With function

With is a very useful function that is included in the standard library of Kotlin. It takes an object and an extension function as its parameters, and then causes the object to extend the function. This means that all the code we write in parentheses is an extension function of the object (the first parameter), and we can use all its public methods and properties as if we were this. This is very helpful to simplify the code when we do a lot of things on the same object.
