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.

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