How to create a Set of integers in TypeScript ?

Answer

To create a set of integers in TypeScript, you can use the Set object.

✐ Examples

1 Create a Set of Integers using Set object

In this example,

We create a new Set object named intSet to store integers.
We use the add() method to add integers to the set.

TypeScript Program

let intSet = new Set<number>();
intSet.add(1);
intSet.add(2);
intSet.add(3);
intSet.add(4);
intSet.add(5);
console.log("Set of integers:", intSet);

Output

Set of integers: Set(5) { 1, 2, 3, 4, 5 }

2 Create a Set of Integers using Set object with Array

In this example,

We create an array named integers containing integers.
We pass the array as an argument to the Set constructor to create the set.

TypeScript Program

let integers: number[] = [1, 2, 3, 4, 5];
let intSet = new Set(integers);
console.log("Set of integers:", intSet);

Output

Set of integers: Set(5) { 1, 2, 3, 4, 5 }

Summary

In this tutorial, we learned How to create a Set of integers in TypeScript language with well detailed examples.
