Immediately Invoked Function Expression | Learn Javascript #javascript #javascriptengineer

In this video, we’ll be learning about the Immediately Invoked Function Expression (IIFE) in Javascript. IIFE is a useful construct that allows us to isolate the scope of a function within its own module. We’ll be looking at examples and getting to grips with how it works.

If you’re interested in learning how to use the Javascript engine effectively, then this video is for you! By the end of this video, you’ll be able to understand and use IIFEs to quickly and easily isolate the scope of functions within your code.

An IIFE (Immediately Invoked Function Expression) is a JavaScript function that runs as soon as it is defined.

It is a design pattern that is also known as a Self-Executing Anonymous Function and contains two major parts:

The first is the anonymous function with lexical scope enclosed within the Grouping Operator (). This prevents accessing variables within the IIFE idiom as well as polluting the global scope.
The second part creates the immediately invoked function expression () through which the JavaScript engine will directly interpret the function.
