Behavior of "this" keywordthis is a weird keyword that behaves a little differently in JavaScript compared to other languages. this serves as an identity function, providing our neighborhoods a way of referring to themselves. this can be used to refer to the object being created by a constructor.
Lambda functions
Lambda expressions simply are expressions that create functions. In JavaScript pre-ES6 we have function expressions that give us an anonymous function (a function without a name).
var anon = function (a, b) { return a + b };
One of the major advantages of arrow functions is that it does not have it's own this value. It's this is lexically bound to the enclosing scope.
