How to get Subset from a Set in TypeScript ?

Answer

To get a sub Set in TypeScript, you can use the slice method.

✐ Examples

1 Get Sub Set with Items

In this example,

We define an array named mySet containing elements of a specific type.
We specify the range of indices to extract the sub Set.
We use the slice() method with the specified range to get the sub Set.

TypeScript Program

// Define array with items
const mySet: string[] = ['apple', 'banana', 'orange', 'grape', 'melon'];

// Get sub Set with items
const subSet: string[] = mySet.slice(1, 4);
console.log('Sub Set with items:', subSet);

Output

Sub Set with items: [ 'banana', 'orange', 'grape' ]

2 Get Sub Set from Empty Set

In this example,

We define an empty array named mySet.
We attempt to get a sub Set from the empty array, which results in an empty sub Set.

TypeScript Program

// Define empty array
const mySet: string[] = [];

// Get sub Set from empty array
const subSet: string[] = mySet.slice(1, 4);
console.log('Sub Set from empty array:', subSet);

Output

Sub Set from empty array: []
