“this” Keyword in GEC, Functions, Objects, Arrow Functions + Strict vs Non-Strict

The this keyword in JavaScript is one of the most confusing topics for beginners because its value changes based on how and where it is used. In this video, we explain the behavior of this in the Global Execution Context (GEC), inside regular functions, strict mode, object methods, arrow functions, and nested functions.

You’ll learn how this refers to the global object in non-strict mode, why strict mode sets it to undefined, how methods inside objects use their own object as this, and how arrow functions inherit this lexically from their surrounding scope.

We also explore how call(), apply(), and bind() can set the value of this manually, and how nested functions behave differently. By the end, you will clearly understand how to control and predict this in any JavaScript scenario.

This video is perfect for beginners who want to strengthen their JavaScript fundamentals with real-world analogies and simple examples.
