javascript-lodashHow do I use Lodash to compare two arrays in JavaScript?


Lodash is a JavaScript library that provides many utility functions for manipulating and working with objects. One of the functions it provides is _.isEqual(), which can be used to compare two arrays in JavaScript.

The _.isEqual() function takes two arguments and returns a boolean value indicating whether the two arguments are equal or not. Here is an example of how to use _.isEqual() to compare two arrays:

let arr1 = [1, 2, 3];
let arr2 = [1, 2, 3];

console.log(_.isEqual(arr1, arr2));

Output example

true

The code above does the following:

  1. Defines two arrays arr1 and arr2 with the same values.
  2. Calls the _.isEqual() function, passing in arr1 and arr2 as arguments.
  3. The _.isEqual() function returns a boolean value indicating whether the two arguments are equal or not. In this case, it returns true since the two arrays are equal.

For more information on Lodash and the _.isEqual() function, see the Lodash documentation.
