Hey Developer,
Welcome to my Javascript blog, My name is Md Taqui Imam i am a Full Stack developer
And in
Today post i will tell you some “Javascript Quick Tips💎” that every javascript developers should know.
1. Combine Objects 👨👨👦👦
const username = { id: '@Taquiimam14' };
const website = { url: 'www.twitter.com' };
const social = { ...username, ...url };
// Result: { id: '@Taquiimam14', url: 'www.twitter.com' }
2. Shuffle an array 🥓
function shuffleArr(array) {
return array.sort( () => Math.random( ) - 0.5) ;
}
let myArr = [1, 2, 3, 4, 5];
shuffleArr(myArr);
// Result: [3, 1, 5, 4, 2]
3. Short-circuit conditional 🛠
// Old
if ( isSubscribed ) {
sendThankyouEmail();
}
// New
isSubscribed && sendThankyouEmail() ;
4. Dynamic Property Names ✨
const dynamic = 'websites' ;
var social = {
userId: '@Taquiimam14',
[dynamic]: 'www.twitter.com'
};
// Result: { userId: "@Taquiimam14", website: "www.twitter.com" }
5. Flattern an array 👓
const oldArr = [1, 2, [2, 3, 4], 8];
const newArr = oldArr.flat();
// Result: [1, 2, 2, 3, 4, 8]
6. Return shorthand ✔

fumction myfunc() {
foo();
bar();
return 1;

function myFunc() {
return foo(), bar(), 1;
}

array.length = 2 ;
// Result: [1, 2]
