How to compare two objects in javascript

Most of the time, you use the == and === operators in JavaScript to compare data types like int and strings. But you can't compare objects with == and ===.

JSON.stringify()

One way to fix this is to turn both objects into strings and then use the equality operators.
First, we use JSON.stringify() to turn the objects into their stringified versions. Then, we use ===: to compare them.

Even though the properties are the same, the above method will return false if the order of the properties is different

Using lodash

Instead, we can use a JavaScript library called lodash to solve this problem.

The _.isEqual(value1, value2) method in the JavaScript library lodash does a deep comparison between two values to see if they are the same.
