Angular is a popular JavaScript framework developed by Google for building web applications. It follows a component-based architecture and uses TypeScript, a statically-typed superset of JavaScript, as its primary language.
AngularJS, on the other hand, is an older version of Angular (referred to as Angular 1.x) that uses JavaScript and follows a directive-based architecture.

Angular directives are markers on DOM elements that allow you to create custom HTML tags or attributes, and attach behavior or functionality to them.
Directives can be classified into three types: Component directives, Attribute directives, and Structural directives.
Component directives are used to create custom components with their own templates, styles, and logic. They are the most commonly used type of directive in Angular.
Attribute directives are used to change the behavior or appearance of an existing DOM element. They can be used to add or modify attributes, styles, or classes of an element.
Structural directives are used to modify the structure of the DOM by adding, removing, or manipulating elements. They use a specific syntax with an asterisk (*) prefix, such as *ngIf and *ngFor.

Data binding in Angular is the process of establishing a connection between the UI (view) and the application logic (component) to keep them in sync.
There are four types of data binding in Angular:
Interpolation: It is a one-way data binding where you can embed expressions in double curly braces ({{ }}) in the template to display dynamic values.
Property binding: It is also a one-way data binding where you can bind the value of a property from the component to the view using square brackets ([]) notation.
Event binding: It is a one-way data binding that allows you to capture and respond to events (e.g., click, change) from the view in the component using parentheses (()) notation.
Two-way binding: It is a two-way data binding that combines property binding and event binding together. It allows you to update the view and component simultaneously. It uses the [(ngModel)] directive in Angular.

Dependency injection (DI) is a design pattern in Angular that allows you to create and manage dependencies between components and services.
DI helps in achieving loose coupling between different parts of an application, making it more modular and maintainable.
In Angular, you can define dependencies as services and inject them into components or other services as needed.
DI also promotes reusability as services can be shared across multiple components, reducing code duplication and improving the overall performance of an application.

Angular templates are used to define the UI (view) of an Angular component. They are written in HTML and can include Angular-specific syntax.
Templates are used to define the structure of the view, data bindings, and event bindings.
Angular uses a declarative approach to templates, where you define what you want to display and how you want to bind the data, and Angular takes care of updating the view automatically when the data changes in the component.
Templates can include directives, which are used to add behavior and functionality to the view.

Angular routing is a mechanism that allows you to navigate between different views or components in a single-page application (SPA) without triggering a full page reload.
Angular uses a built-in module called RouterModule to handle routing.
Routing in Angular is based on the URL patterns, and you can define routes that map to specific components or views.
Angular routing allows you to create single-page applications with multiple views, handle navigation, and pass parameters to components for dynamic content rendering.

Angular decorators are special types of TypeScript annotations that are used to add metadata to classes, methods, and properties, which Angular uses to provide additional functionality.
Decorators are used to mark Angular components, directives, pipes, services, and modules.
Angular provides several built-in decorators, such as @Component, @Directive, @Pipe, @Injectable, @NgModule, etc., which are used to define and configure different parts of an Angular application.
Custom decorators can also be created to extend the functionality of Angular components or services.
