🔧 🚀 JavaScript Functions: Arrow Functions, Callbacks, and Closures 📜

Hey, JavaScript enthusiasts! 🌟 Ready to dive into the world of functions?

Let’s break it down with some cool concepts you’ll use all the time!

1. Arrow Functions ➡️

Say goodbye to long function syntax! Arrow functions are short and sweet 😎.

Plus, they handle this a bit differently.

const add = (a, b) => a + b;

No more typing function! Less is more, right? 🤩

1. Callbacks 📞

Callbacks are like passing notes between functions. One function calls another when it’s ready!

They’re super helpful for tasks that take time, like fetching data from a server.

function processUserInput(callback) {

 const name = prompt('Enter your name');

 callback(name);

}

Just drop the callback like it’s hot 🔥!

1. Closures 🔒

Closures are like function vaults—securely storing variables even after the function is done. Need access to an old variable? Closures have your back 💼!

function outer(outerVar) {

 return function inner(innerVar) {

  console.log(outerVar, innerVar);

 };

}

Unlock the power of closures in your code 🔓!

Pro Tip: Mastering these will take your JavaScript skills to the next level! 🏆 Keep coding, keep learning! 💻💡
