In this video, we dive into the power of JavaScript’s “this” keyword and explore how it can be used to create a simple library for DOM manipulation and animation. With the help of examples and explanations, you’ll learn how to leverage “this” in combination with “apply”, “call”, and “bind” to build your own jQuery-like functionality.

We start by understanding the concept of “this” and its role in JavaScript. Then, we demonstrate how to create a lightweight library called miniQuery using the “this” keyword. The library allows you to select DOM elements, add classes dynamically, and apply fade-in and fade-out animations.

Throughout the video, we explain each step in detail and provide clear code examples. By the end, you’ll have a solid understanding of “this”, apply”, “call”, and “bind”, as well as how to create your own DOM manipulation library.
