What is the purpose of the common module in Angular?

The common module in Angular, which is accessible in the package @angualr/common, is a module that contains all of Angular’s widely used features, such as services, pipes, directives, and so on. It also includes sub-modules, such as the HttpClientModule, which is part of the @angular/common/http package. Because of Angular’s modular design, its capabilities are kept in small self-contained modules that may be imported and incorporated into our applications if they are required.
