What is benefit of page object model?

I want to know the basic benefits of page object model

The Page Object Model has the following advantages:

  1. Code Reusability: POM makes code more reusable. Teams can create shared methods that can be used across several web pages. For instance, suppose a web application has calendar functionality on various web pages. As a result, we can construct a single method to handle the calendar functionality and apply it to all page classes.

  2. Code Readability: POM improves code readability by storing each web page’s Locators, Methods, and Test Steps in its own class file.

  3. Code Maintenance: POM makes code maintenance simple. If any changes are needed, we may make them directly at the method level (the common method), and the changes will be reflected elsewhere.
