The Page Object Model (POM) is a design pattern in Selenium that is used to create object-oriented classes that serve as an interface to interact with the pages of a web application. It helps in organizing and simplifying the code by representing each page of an application as a separate class with methods that perform actions on that page or retrieve data from it.
