HTML5 presents a lots of useful features in new APIs that make this most popular among web designers and developers in just few years. A number of tools are available over the internet to create interactive & effective web applications. Also have a number of highly useful APIs that help developers to create effective websites with some great features like – online video games, page visibility, testing the performance of code, measure the performance of applications and much more.

Visit this list, i hope you will love to use these APIs in your next projects.


1) HTML5 APIs –  User Timing API 

This specification defines an interface to help web developers measure the performance of their applications by giving them access to high precision timestamps. Web developers need the ability to assess and understand the performance characteristics of their applications. the PerformanceMark and PerformanceMeasure interfaces, and extensions to the Performance interface, which expose a high precision timestamp to developers so they can better measure the performance of their applications.

This specification defines a JavaScript API to enable web developers to incorporate speech recognition and synthesis into their web pages. It enables developers to use scripting to generate text-to-speech output and to use speech recognition as an input for forms, continuous dictation and control. The JavaScript API allows web pages to control activation and timing and to handle results and alternatives.

8) HTML5 API – Page Visibility

The Page Visibility specification defines a means for site developers to programmatically determine the current visibility of a document and be notified of visibility changes. Without knowing the visibility state of a page, web developers have been designing webpages as if they are always visible.
