How to Split an Array in JavaScript ?

Answer

To split an array in JavaScript, you can use the split method or the slice method.

✐ Examples

1 Splitting an Array using split Method

In this example,

We create an array named numbers with elements separated by commas.
We then use the split method to split numbers into an array of strings.
The split method returns an array of strings.

JavaScript Program

const numbers = '1,2,3,4,5,6,7,8,9';
const chunks = numbers.split(',');
console.log(chunks);

Output

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

2 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.

JavaScript 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 ] ]
