How to Split an Array in TypeScript ?

Answer

To split an array in TypeScript, you can use the slice method or the destructuring assignment.

✐ Examples

1 Splitting an Array using slice Method

In this example,

We create an array named numbers with integer elements.
We then use the slice method to split numbers into slices based on indices.
The slice method returns a new array representing the sliced elements.

TypeScript Program

const numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9];
const slices = [numbers.slice(0, 3), numbers.slice(3, 6), numbers.slice(6, 9)];
console.log(slices);

Output

[ [ 1, 2, 3 ], [ 4, 5, 6 ], [ 7, 8, 9 ] ]

2 Splitting an Array using destructuring Assignment

In this example,

We create an array named numbers with integer elements.
We then use destructuring assignment to split numbers into slices based on indices.
The destructuring assignment assigns sliced elements to new variables.

TypeScript Program

const numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9];
const [slice1, slice2, slice3] = [numbers.slice(0, 3), numbers.slice(3, 6), numbers.slice(6, 9)];
console.log(slice1, slice2, slice3);

Output

[ 1, 2, 3 ] [ 4, 5, 6 ] [ 7, 8, 9 ]
