In Angular, a directive is a class that can modify or enhance the behavior of HTML elements. Directives can be used to add, remove, or modify the DOM elements and their behavior, as well as to provide additional functionality to the components.
There are three types of directives in Angular:
Component Directive - A component directive is used to create a new custom element that can be used as a regular HTML tag.
Structural Directive - A structural directive is used to manipulate the layout of the HTML elements. They are used to add or remove elements from the DOM based on certain conditions.
Attribute Directive - An attribute directive is used to change the behavior of an existing element by modifying its attributes or behavior.
Directives can be declared in the Angular module, component or any other TypeScript file, and can be used in the HTML templates of the components. Directives are one of the key features of Angular that allow developers to create reusable components and enhance the functionality of the HTML elements.
