And what is the value of the 'this' keyword, it depend on where is called. Inside an object method, it returns this object. But remember only working within the object method not any object property. otherwise, it is not inside any object its return window object or undefined.If we are use it in a strick mode in a function its return undefine.Arrow function can not working with this keyword.
