Lodash _.nth() method is used to return the nth index of the element. For a negative value of n, it returns the nth element from the end.
Syntax:
_.nth(array, n);
Parameters:
- array: This parameter holds the query array.
- n: This parameter holds the index of the element that is to be extracted.
Return Value:
It returns the nth element of the array.
Example 1: In this example, It returns the third element of an array.
javascript
const _ = require( 'lodash' );
let ar = [1, 2, 3, 4, 5]
let value = _.nth(ar, 3)
console.log(value)
|
Output:
4
Example 2: In this example, It returns the third element from the end of an array because the value of n is negative.
javascript
const _ = require( 'lodash' );
let ar = [1, 2, 3, 4, 5]
let value = _.nth(ar, -3)
console.log(value)
|
Output:
3
Example 3: In this example, It returns undefined because there is no element at index 8.
javascript
const _ = require( 'lodash' );
let ar = [1, 2, 3, 4, 5]
let value = _.nth(ar, 8)
console.log(value)
|
Output:
undefined
