_.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 nth 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:

4

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:

3

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
