The equality operator converts operands to the same type before comparing them. For example:14const assert = require('assert');15const value1 = 'abc';16const value2 = 'abc';17Note: The deepEqual method is different from the strict equality operator ( === ). The deepEqual method performs a deep comparison between two values to determine if they are equivalent. For example:18const assert = require('assert');19const value1 = '1';20const value2 = 1;

However, there are certain scenarios where you might want to use the Playwright Internal API. This is a great way to extend the capabilities of the Playwright API. In this article, we will learn how to use the Playwright Internal API and compare the screenshots of two web pages using the Playwright Internal API. Let’s get started!Before we get started, let’s understand what the Playwright Internal API is. The Playwright Internal API is a set of methods that are not available in the Playwright API. These methods are used by the Playwright API to perform certain tasks. However, these methods are not documented and are not intended to be used by the end-user. The Playwright Internal API can be accessed by importing the Playwright library and then accessing the Playwright Internal API methods. For example, to access the Playwright Internal API methods, you can use the following code:In the above code, we have imported the Playwright library and then accessed the Playwright Internal API methods. The Playwright Internal API methods are available under the lib/utils/utils.js file. You can access the Playwright Internal API methods by importing the Playwright library and then accessing the Playwright Internal API methods under the
