π‘IIFE?
β IIFE stands for Immediately Invoked Function Expression.
β IIFE is an anonymous JavaScript function that executes as soon as it's defined.
β It is also known as a "self-executing anonymous function".

β IIFE is an anonymous JavaScript function that executes as soon as it's defined.
β It is also known as a "self-executing anonymous function".
β Suppose you do not want to store a function in a window object or you do not want to use a process once used.
β So we can use "Immediately Invoked Function Expression" to achieve this goal.

π‘ Syntax of IIFE:
β anonymousFunction: we have to define an anonymous function inside the parentheses(grouping operator).
β invoking: after defining an anonymous function, we can call/invoke that function using the grouping operator (parentheses).
β anonymousFunction: we have to define an anonymous function inside the parentheses(grouping operator).
β invoking: after defining an anonymous function, we can call/invoke that function using the grouping operator (parentheses).
π Example:
β I've created an anonymous function and I want to execute this function using IIFE.
β So, we have to wrap this function into parentheses(grouping operator)
β I've created an anonymous function and I want to execute this function using IIFE.
β So, we have to wrap this function into parentheses(grouping operator)
β We have to wrap the anonymous function into parentheses like this. π
π‘ Now it's a function. So we can quickly call/run/invoke this function as a regular function using parentheses.

β I called this function and also passed 2 arguments to the function, which are 10 and 20.
β And the result is 30.
π But we can also implement this function expression using an arrow function.
