1310How does lodash.nth work?
lodash.nth works by taking an array as its first argument, and a number (the index) as its second argument. The index argument determines which element of the array will be returned. A negative index can also be used to count backwards from the end of the array. If the index is out of range (greater than or equal to the length of the array, or less than the negative length of the array), the function returns undefined. Here is the syntax for lodash.nth: c Copy code {{{{{{{ class="!whitespace-pre hljs language-c">_.nth(array, [n=0]) And here is a breakdown of the arguments: array (Array): The array to query. [n=0] (number): The index of the element to return. Here's an example of how lodash.nth can be used to return the nth element of an array: javascript Copy code {{{{{{{ const _ = require('lodash'); const arr = ['a', 'b', 'c', 'd']; console.log(_.nth(arr, 1)); // Output: 'b' console.log(_.nth(arr, -2)); // Output: 'c' In this example, _.nth(arr, 1) returns the second element of the arr array ('b'), while _.nth(arr, -2) returns the third-to-last element of the arr array ('c').

In this example, we create an array of fruits and pass it to _.nth along with the index value of 2. This returns the third element of the array ('cherry'). We also pass the index value of -1, which returns the last element of the array ('elderberry').
