*Function Expressions* with Anonymous functions, IIFE & Hoisting | JavaScript Basics

In this video, we'll be diving into one of the core concepts of JavaScript: Function Expressions. Rohan with @DecodeWebWithRohan will explore the world of JavaScript functions, including expressions, declarations, and hoisting. We'll start with an explanation of what an expression is and then dive into the differences between function declarations and function expressions, including anonymous and named function expressions. We'll also discuss the importance of understanding hoisting in JavaScript, including function hoisting and variable hoisting. Finally, we'll compare and contrast the benefits of defining functions and then calling them vs using immediately invoked function expressions (IIFEs). By the end of this video, you'll have a solid understanding of the different types of JavaScript functions and how to use them in your own code. So, let's get started!
