Lodash _.nth() Method

0 0 1 minute read

The _.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: This method accepts two parameters as mentioned above and described below:

Array: This parameter holds the query array.
n: This parameter holds the index of element that to be extracted.

Return Value: It returns the n^th element of the array.

Example 1: 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)

Here, const _ = require('lodash') is used to import the lodash library into the file.

Output:

Example 2: 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:

Example 3: 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
