# AngularJS API Docs
<div class="alert alert-warning">
AngularJS support has officially ended as of January 2022.
[See what ending support means](https://docs.angularjs.org/misc/version-support-status)
and [read the end of life announcement](https://goo.gle/angularjs-end-of-life).

Visit [angular.io](https://angular.io) for the actively supported Angular.
</div>

## Welcome to the AngularJS API docs page.

These pages contain the AngularJS reference materials for version <strong ng-bind="version"></strong>.


The documentation is organized into **{@link guide/module modules}** which contain various components of an AngularJS application.
These components are {@link guide/directive directives}, {@link guide/services services}, {@link guide/filter filters}, {@link guide/providers providers}, {@link guide/templates templates}, global APIs, and testing mocks.

There is also a {@link guide/index guide} with articles on various topics, and a list of external resources.

<div class="alert alert-info">
**AngularJS Prefixes `$` and `$$`**:

To prevent accidental name collisions with your code,
AngularJS prefixes names of public objects with `$` and names of private objects with `$$`.
Please do not use the `$` or `$$` prefix in your code.
</div>

## AngularJS Modules


## {@link ng ng (core module)}
This module is provided by default and contains the core components of AngularJS.

<table class="definition-table spaced">
  <tr>
    <td>{@link ng#directive Directives}</td>
    <td>
      <p>
        This is the core collection of directives you would use in your template code to build an AngularJS application.
      </p>

      <p>
        Some examples include:
          {@link ng.directive:ngClick ngClick},
          {@link directive:ngInclude ngInclude},
          {@link directive:ngRepeat ngRepeat},
          etc… <br />
      </p>
    </td>
  </tr>
  <tr>
    <td>
      {@link ng#service Services / Factories}
    </td>
    <td>
      <p>
        This is the core collection of services which are used within the DI of your application.
      </p>
      <p>
        Some examples include:
          {@link ng.$compile $compile},
          {@link ng.$http $http},
          {@link ng.$location $location},
          etc…

    </td>
  </tr>
  <tr>
    <td>
      {@link ng#filter Filters}
    </td>
