He does not seem to be having 8 YOE alone with Front End !! He is so nervous, even after having so much years of experience in the bucket. !!

It's ok definition but this is experiene interview you must deev dive into actual meaning , javascript is totally based on objects when you try to access some properties which is not defined yet javascript prototype chain work its looks on objects.prototype.prototype if not found they return undefined , this problem short out with let key it will not bound to global object , let will also solve of re declartion issue you can't declare same variable twice in program

Brilliant way of speaking brother. You must be a great team mate to work along. I love the video. I learnt a lot.

Good content helpful. Recently I have given interviews for experienced fullstack developer, where they are focusing on polyfills, explicit method binding, array functions and "this" - out based, machine coding as well. can you create contents on them, that will be helpful.

Beautiful interviews Vasanth, really liked it.

@@careerwithvasanth only when parent re-renders or state change. Or in case of context or redux like state management changes, its a misconception that a component re-renders upon prop changes

More series I will be doing when I reach 5000 Subscribers, thus video could to reach to many !!

var length = 10; function fn(){ console.log(this.length); } var obj={ length:5, method:function (fn){ fn(); arguments[0](); } } obj.method(fn,10) I'll try to explain the output. The output is 10, 2. For which explanation is as simple as when you say at the first chance that Arrays in JavaScript are objects. Being objects means that arrays' indices are the keys, and whenever we store a function in an array these are the methods only with the key being a number. Here when fn is called, it references to the lexical scope of 'fn' and in that case, it is the window object in non-strict mode. When you call it like arguments[0](), evaluation of arguments[0] happens and it evaluates to the function 'fn' that is then called as a method in the arguments Array( or Object). As in method calling, in the method 'this' evaluates to the object on it is called, arguments is that object here and hence this.length evaluates to arguments.length that is 2 here.
