How to find Union of Two Sets in JavaScript ?

Answer

In JavaScript, you can find the union of two sets using the Set data structure and the spread operator or the forEach loop.

✐ Examples

1 Union of Two Sets using Spread Operator

In this example,

We create two sets named set1 and set2.
We use the spread operator (...) to merge set2 into set1.

JavaScript Program

let set1 = new Set([1, 2, 3]);
let set2 = new Set([3, 4, 5]);
set1 = new Set([...set1, ...set2]);
console.log('Union of set1 and set2:', set1);

Output

Union of set1 and set2: Set { 1, 2, 3, 4, 5 }

2 Union of Two Sets using forEach Loop

In this example,

We create two sets named set1 and set2.
We iterate over set2 using the forEach loop and add each element to set1.

JavaScript Program

let set1 = new Set([1, 2, 3]);
let set2 = new Set([3, 4, 5]);
set2.forEach(element => {
    set1.add(element);
});
console.log('Union of set1 and set2:', set1);

Output

Union of set1 and set2: Set { 1, 2, 3, 4, 5 }
