In old ec,
a = a+b
b=a-b
a=a-b
And values are swipped. But new ec made it very simple.

[examtak]

Thank you dai sarai ramro sikhaunu huncha 😘

[kirtisharma]

We can also..perform this by both two
a=a+b;
b=a-b;
a=a-b;
document.write(a+", "+b);

[shubhamsingh]

great work bro we need more problem solving question thanks

[singh]

<script>
let a=10;
let b=5;
a=a+b;
b=a-b;
a=a-b;
alert(`after swapping value will be a : ${a} and value of b : ${b}`);

</script>

[bishaldutta]

Great Work Mr. Thapa...We need more people like you who shares knowledge free of cost... (Eg: b = (b = a + (a=b))-a;) this logic works with other languages also:)

[zafarhussain]

it's very useful while using implementing data structure

[fuzailakhtar]

var a = 1;
var b = 3;

[a, b] = [b, a];
console.log(a); // 3
console.log(b); // 1

[vinaydixit]

let a=8;
let b=4;

a=a+b;
b=a-b;
a=a-b;

console.log(a);
console.log(b);

[hamadjan]

Var a=5;
Var b=10;
a=b; b=a;

Also works

[ahmednisar]

let a = 10;
let b = 20;

[a, b] = [b, a]

console.log(`value of a is: ${a}`)
console.log(`value of b is: ${b}`)

[RitikKumar-bkpj]

A =5;
B =3;
A = A ^ B;
B = A ^ B;
A = A ^ B;

[jayprajput]

let a = [10];
let b = [20];

[a, b] = [b, a];
console.log(`value of a = ${a} and value of b = ${b}`);

output :-

value of a = 20 and value of b = 10

[praveenkrgola]

Could not find Array Destructure video,

[pallavraj]

let x = 20;
let y = 30;
console.log(`Value of x is ${x} and y is ${y}.`);
console.log(`Swap value of x is ${(x+y)-x} and y is ${(x+y)-y}`);
