Lodash _.nth() Method

Lodash _.nth() method is used to return the n^th index of the element. For a negative value of n, it returns the n^th 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 n^th element of the array.

Example 1: In this example, It returns the third element of an array.

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.

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.

const _ = require('lodash');

let ar = [1, 2, 3, 4, 5]
let value = _.nth(ar, 8)

console.log(value)

Output:

undefined
