How to get Sub Array in JavaScript - Step by Step Examples
How to get Sub Array in JavaScript ?
Answer
To get a sub-array in JavaScript, you can use the `slice` method of arrays.
✐ Examples
1 Sub-array of Integer Array
In this example,
- We create an integer array named
numbers
with some values. - We then use the
slice
method to get a sub-array from index 2 to index 4 (exclusive). - The
slice
method returns a new array with the specified range. - Finally, we log the sub-array to the console.
JavaScript Program
const numbers = [1, 2, 3, 4, 5];
const subArray = numbers.slice(2, 4);
console.log('Sub-array:', subArray);
Output
Sub-array: [ 3, 4 ]
2 Sub-array of String Array
In this example,
- We create a string array named
colors
with some values. - We then use the
slice
method to get a sub-array from index 1 to index 3 (exclusive). - The
slice
method returns a new array with the specified range. - Finally, we log the sub-array to the console.
JavaScript Program
const colors = ['red', 'green', 'blue', 'yellow', 'orange'];
const subArray = colors.slice(1, 3);
console.log('Sub-array:', subArray);
Output
Sub-array: [ 'green', 'blue' ]
