# AngularJS Cheatsheet
## Overview
- AngularJS is a JavaScript framework for building dynamic web applications.
- It uses a Model-View-Controller (MVC) architecture to organize code and provide separation of concerns.
- AngularJS is often used for single-page applications (SPAs) and is known for its two-way data binding and dependency injection.
## Directives
- Directives are markers on a DOM element that tell AngularJS to attach a specific behavior to that element.
- Directives can be used to create custom HTML tags, attributes, and classes.
- Some common directives include `ng-app`, `ng-model`, `ng-repeat`, and `ng-click`.
## Controllers
- Controllers are JavaScript functions that are responsible for controlling a part of the UI.
- Controllers can be used to set up the initial state of the scope, handle user input, and respond to events.
- Controllers can be defined using the `controller` method.
## Services
- Services are objects that provide functionality to an AngularJS application.
- Services can be used to share data between controllers, handle HTTP requests, and perform other common tasks.
- Services can be defined using the `service` method.
## Filters
- Filters can be used to format data for display in the UI.
- Some common filters include `currency`, `date`, `uppercase`, and `lowercase`.
- Filters can be chained together to create more complex transformations.
