How to do a deep comparison between two objects using Lodash

Overview

In Lodash, we can deeply compare two objects using the _.isEqual() method. This method will compare both values to determine if they are equivalent.

Syntax

Parameters

This method accepts the following parameters:

• value1: This is the value to be compared.
• value2: This is the other value to be compared.

Return value

This method returns true if both values are equivalent, and vice-versa.

Example

Let’s look at an example of a deep comparison between two objects using the _.isEqual() method in the code snippet below.

Explanation

In the HTML tab, we see the following:

• Line 5: We import the lodash script.

In the JavaScript tab, we see the following:

• Line 2–14: We create three objects, namely obj1, obj2, and obj3 respectively, and initialize them.

• Line 17: We do a deep comparison between obj1 and obj2 and print the result on the console.

• Line 18: We do a deep comparison between obj1 and obj3 and print the result on the console.
