Hello Everyone, in this article you will see Top JavaScript Shorthands Techniques to speed up your tasks

1. Declare more than one variable in one line

let a = 1;
let b = 2;
let c = 3;

let a=1,b=2,c=3;

2. The Ternary Operator

if you want to write if else statement in one line you can use the ternary operator

let x = 30

if(x > 20){
    console.log("greater than 20")
}
else {
    console.log("less than 20")
}

let x = 12;
    x>10 ? console.log("greater than 20") : console.log("less than 20")

let a = 1;
let b = 2;
let c = 3;

let [a,b,c ] = [1,2,3]

let languages = ["JS","Python","PHP"]
    for(let i = 0 ; i<languages.length ; i++){
        console.log(languages[i])
}

for (let language of languages){
        console.log(language)
}

If you just wanted to access the index :

for (let language in languages){
        console.log(language)
}

this shorthand work if the variable name is the same as the object key

 let name = "mostafa";
 let age = 17;
 let myinfo = {
        name : name,
        age : age
    };

 let name = "mostafa";
 let age = 17;
let myinfo = {name, age}

 let a = 20;
let b = 30;

let temp = a;
a = b
b = temp

let a = 20;
let b = 30;
[a,b] = [b,a]
