How to Initialize a Set in TypeScript


How to Initialize a Set in TypeScript ?

Answer

To initialize a set in TypeScript, you can use the Set object.



✐ Examples

1 Initialize an Empty Set

In this example,

  1. We use the Set constructor, which is a built-in constructor in TypeScript, to create a new, empty set.
  2. We declare a variable named set1 and assign it the result of calling the new Set() constructor.
  3. The new Set() constructor creates an empty set.
  4. We then print the set1 to the console to verify its contents. An empty set in TypeScript is represented as Set {}.

TypeScript Program

const set1 = new Set();
console.log('Contents of set1:', set1);

Output

Contents of set1: Set {}

2 Initialize a Set with Elements

In this example,

  1. We use the Set constructor to create a new set and initialize it with elements.
  2. We declare a variable named set2 and assign it the result of calling the new Set() constructor with an iterable such as an array containing elements.
  3. We then print the set2 to the console to verify its contents.

TypeScript Program

const set2 = new Set(['apple', 'banana', 'cherry']);
console.log('Contents of set2:', set2);

Output

Contents of set2: Set { 'apple', 'banana', 'cherry' }
