Types of Functions in Javascript

bhattabbk

I am confused about function types in JS. How many types of functions do i need to know before i dive into the world of web development? basically, while going through you tube tutorials on JS,i found out several types of functions namely constructor functions and factory functions.
i wanted to know how many types of functions are there and what is the difference between them? do i need to learn every function in web development?

bhattabbk How many types of functions do i need to know before i dive into the world of web development?

None. You need to know none. That's what the purpose of learning is, you dive head in and learn as you go. I think you're conflating function declaration vs what a function actually is. There's tons of different ways to define a function function xyz() {} or xyz = function() {} and this list can go on for quite some time. Stay basic, follow tutorials, and learn as you go.

bhattabbk do i need to learn every function in web development?

No. This would be impossible. A function is a programmer or language defined operation, you cannot simply learn every function in existence.

There are three types of Functions available in JavaScript

Named function
Anonymous function
Immediately invoked function expression. It runs as soon as the browser finds it.

But, above as you said to dive in web development that means you are fresher in the technology industry. So, as a fresher, you don't need to know exactly all the functions in Javascript. I don't mean that you don't have to learn these functions but you can learn just there basics.
