Hey, JavaScript enthusiasts! ๐ Ready to dive into the world of functions?
Letโs break it down with some cool concepts youโll use all the time!
- Arrow Functions โก๏ธ
Say goodbye to long function syntax! Arrow functions are short and sweet ๐.
Plus, they handle this
a bit differently.
const add = (a, b) => a + b;
No more typing function! Less is more, right? ๐คฉ
- Callbacks ๐
Callbacks are like passing notes between functions. One function calls another when itโs ready!
Theyโre 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 itโs hot ๐ฅ!
- Closures ๐
Closures are like function vaultsโsecurely storing variables even after the function is done. Need access to an old variable? Closures have your back ๐ผ!
function outer(outerVar) {
return function inner(innerVar) {
console.log(outerVar, innerVar);
};
}
Unlock the power of closures in your code ๐!
Pro Tip: Mastering these will take your JavaScript skills to the next level! ๐ Keep coding, keep learning! ๐ป๐ก
