Introduction to Angular Routing Angular Router enables navigation from one view to another as users perform tasks in your single-page applications (SPAs). Instead of loading entirely new pages from the server, the router enables a “virtual page navigation” experience where only the necessary components are loaded and displayed while the rest of the page remains

Introduction to Angular Directives Directives in Angular are classes that add additional behavior to elements in your Angular applications. They are one of the most powerful features in Angular, allowing you to manipulate the DOM, apply conditional rendering, create repeating elements, and more.
