javascript-lodashHow can I use Lodash to compare two arrays of objects in JavaScript?

Lodash is a JavaScript library that provides utility functions for common programming tasks. It can be used to compare two arrays of objects in JavaScript using the _.isEqual() method.

Example code

let array1 = [{name: 'Bob', age: 20}, {name: 'John', age: 30}];
let array2 = [{name: 'Bob', age: 20}, {name: 'John', age: 30}];

console.log(_.isEqual(array1, array2));

Output example

true

The _.isEqual() method takes two arrays as parameters and returns true if their values are the same, and false otherwise. In this example, the two arrays are identical, so the method returns true.

Code explanation

• let array1 = [{name: 'Bob', age: 20}, {name: 'John', age: 30}]; - This creates an array of objects with two elements. Each element has a name and age property.
• let array2 = [{name: 'Bob', age: 20}, {name: 'John', age: 30}]; - This creates a second array of objects with two elements. The values of the elements are the same as the first array.
• console.log(_.isEqual(array1, array2)); - This uses the Lodash _.isEqual() method to compare the two arrays. It takes two parameters, which are the two arrays, and returns true if the values are the same, and false otherwise.
