How to Clone a Set in JavaScript ?

In JavaScript, you can clone (create a shallow copy of) a Set using the spread operator (...) or the Set constructor. Here are two common methods for cloning a Set:

Method 1: Using the Spread Operator

Here, the spread operator is used to create a new Set (clonedSet) with the elements of the original Set (originalSet).

let originalSet = new Set([1, 2, 3, 4, 5]);

// Clone the set using the spread operator
let clonedSet = new Set([...originalSet]);

console.log(clonedSet); // Output: Set { 1, 2, 3, 4, 5 }

Method 2: Using the Set Constructor

Here, the Set constructor is used with the original Set as an argument to create a new Set (clonedSet). This method works because the Set constructor can accept an iterable object, and a Set is iterable.

let originalSet = new Set([1, 2, 3, 4, 5]);

// Clone the set using the Set constructor
let clonedSet = new Set(originalSet);

console.log(clonedSet); // Output: Set { 1, 2, 3, 4, 5 }
