Angular is an open source JavaScript framework that makes it easier to create big applications. It provides high performance scores and decouples components from dependencies. This means developers can build applications with complex logic.
Angular supports two-way data binding, which synchronizes data between a view component and a model. This reduces development time and eliminates writing additional code. It also makes unit testing easier.
The Angular framework consists of components, services, and directives. Each component is a class that contains application data. Each component also defines an HTML template.
Components are written in TypeScript. The template uses binding markup to combine ordinary HTML with Angular directives. The HTML is converted into JavaScript instructions and interpreted by the renderer. The template can also use pipes to transform values for display.
Angular uses a model-view-controller (MVC) architecture. The model component is initialized in the controller. Its properties are defined in the scope object. The scope object acts as a glue between the controller and the view. The scope object also reflects changes in the DOM.
The controller class evaluates HTML expressions. It can respond to user input or custom access rules. It also can decide which views to show or hide. It also has a built-in service, the Router service, which provides sophisticated in-browser navigation capabilities.

Angular’s directives are markers on DOM elements. They allow engineers to create custom HTML tags. They also enabled a developer to assign special behaviors to DOM elements. They can be divided into structural directives, which alter DOM layout, and attribute directives, which alter DOM appearance.
