Making web pages interactive
- Creating buttons that will respond to a hovering mouse cursor. This can include changing color or showing or hiding additional information
- Embedding Google search boxes, YouTube videos, or scrolling multimedia playlists
- Allowing users to zoom in or zoom out on images or other content on the page
- Loading documents for a user without having to reload the entire web page
- Creating a variety of interactive menus, including drop-downs, hamburger menus, and more
- Displaying animations on the web page
- Validating data entered into websites for sign-up forms
Creating web and mobile applications
Typically, there are two types of APIs:
- Browser APIs
Browser APIs are built into web browsers and can do complex things (like audio processing and effects) with the data from the browser and surrounding computer environment.
- Third-party APIs
Third-party APIs are, by contrast, not built into a browser and you have to get their information from a third-party online. Most social media platforms, for example, will have their own API, allowing you to display things like posts and tweets on web pages.
