Structural Directives in Angular: Manipulating the DOM for Dynamic Content Rendering

Описание: In Angular, a structural directive is a type of directive that allows you to add, remove, or manipulate elements in the DOM based on a condition. Structural directives are distinguished from attribute directives, which modify the behavior or appearance of existing elements.

Structural directives are used to build dynamic and flexible templates in Angular. They typically start with an asterisk (*) before the directive name, which is why they are also known as "star" directives.

Some common structural directives in Angular are:

*ngIf: Conditionally renders an element or group of elements based on a boolean expression.

*ngFor: Iterates over a collection of items and renders a template for each item.

*ngSwitch: Conditionally renders a template based on the value of an expression.

*ngTemplateOutlet: Renders a template and replaces the current element with the contents of the template.

Structural directives are used extensively in Angular templates to build dynamic and reactive user interfaces. By defining the structure of the DOM based on data and conditions, structural directives allow you to create templates that are responsive and easy to maintain.
