Mar 21, 2023 · An immediately invoked function expression, or IIFE (pronounced iffy), is a function that is called immediately after it is defined. While it may seem peculiar, creating functions that behave in such a way can actually benefit the code that we write.

5. It is a function expression, it stands for Immediately Invoked Function Expression (IIFE). IIFE is simply a function that is executed right after it is created. So insted of the function having to wait until it is called to be executed, IIFE is executed immediately. Let's construct the IIFE by example.
IIFE is a design pattern that is also known as the Self-Executing Anonymous Function.
