JavaScript most asked interview question: #9 How Can You Handle Exceptions With Javascript? Using try…catch…finally 👈 try statement: defines the code you want to run catch statement: handle errors finally statement: code you want to run regardless of any errors I have created an e-book in a well structured way which will help to answer these questions without any problems.

JavaScript most asked interview question: "this" 👉 "this" refers to the current object!!! In details - The value of this in JavaScript depends on how a function is invoked (runtime binding), not how it is defined. When a regular function is invoked as a method of an object (obj.method()), this points to that object. When invoked as a standalone function (not attached to an object: func()), this typically refers to the global object (in non-strict mode) or undefined (in strict mode). The Function.prototype.bind() method can create a function whose this binding doesn't change, and methods Function.prototype.apply() and Function.prototype.call() can also set this value for a particular call. Arrow functions differ in their handling of this: they inherit this from the parent scope at the time they are defined. This behavior makes arrow functions particularly useful for callbacks and preserving context. However, arrow functions do not have their own "this" binding. Therefore, their this value cannot be set by bind(), apply() or call() methods, nor does it point to the current object in object methods. I have created an E-Book in a well structured way which will help to answer and write logic to these questions without any problems.

JavaScript Important Interview Question # 10 : Scope In JS ***Imp*** Guess the output of the below code? (function () {   var a = b = 3; })(); console.log("a defined? " + (typeof a !== "undefined")); //false console.log("b defined? " + (typeof b !== "undefined")); //true You should understand JavaScript internals, how variables will act during inside or outside and how they get assigned with values. var = a = b = 3 => JS engine will convert them like this b = 3 => global scope => hoisted inside global object var a = b => function scope If variables are hoisted in global space, those can be accessed anywhere in the program. If variables comes under function scope will not be accessible outside of that function.
