How to Copy a Set in TypeScript ?

Answer

In TypeScript, you can copy a Set by creating a new Set and using the spread operator or the Set constructor.

✐ Examples

1 Copy a Set using Spread Operator

In this example,

We have an existing Set named originalSet with some elements.
We create a new Set named copiedSet using the spread operator [...originalSet].
The spread operator creates a new Set with the same elements as the original Set.

TypeScript Program

let originalSet: Set<string> = new Set(["apple", "banana", "cherry"]);
let copiedSet: Set<string> = new Set([...originalSet]);
console.log("Original Set: ", originalSet);
console.log("Copied Set: ", copiedSet);

Output

Original Set: Set(3) { 'apple', 'banana', 'cherry' }
Copied Set: Set(3) { 'apple', 'banana', 'cherry' }

2 Copy a Set using Set Constructor

In this example,

We have an existing Set named originalSet with some elements.
We create a new Set named copiedSet using the Set constructor new Set(originalSet).
The Set constructor creates a new Set with the same elements as the original Set.

TypeScript Program

let originalSet: Set<string> = new Set(["apple", "banana", "cherry"]);
let copiedSet: Set<string> = new Set(originalSet);
console.log("Original Set: ", originalSet);
console.log("Copied Set: ", copiedSet);

Output

Original Set: Set(3) { 'apple', 'banana', 'cherry' }
Copied Set: Set(3) { 'apple', 'banana', 'cherry' }
