    Re: What is ‘this’ keyword in JavaScript?

    In JavaScript, the thing called this, is the object that "owns" the JavaScript code. The value of this, when used in a function, is the object that "owns" the function. The value of this, when used in an object, is the object itself.

    The (this) keyword is one of the most widely used and yet confusing keyword in JavaScript. (this) keyword points to a particular object. Now, which is that object is depends on how a function which includes 'this' keyword is being called.

    JavaScript is the programming or scripting language and it creates dynamically control multimedia, animated images. ‘This’ keyword is powerful global object & it is one of the most misunderstood parts of JavaScript and this keyword is using for execution the context. For example:-
    function f1() {
    return this;
    }
    // In a browser:
    f1() === window; // true
    // In Node:
    f1() === global; //

    This keyword in an object constructor does not have a value. It is only a substitute for the new object.The value of this will become the new object when the constructor is used to create an object.
