Web developers prefer to use HTML5 since it involves using a simpler and shorter code. This will enable web pages to run smoother and faster without any mistakes being made in coding. There are some HTML5 features that web developers can use- Canvas, Video, Application Caches, and Web Workers.

Canvas: It allows a web developer to deliver graphics and does not require a plugin.

Video: Videos can be embedded without the need for any added plugins.

Application Caches: It allows for storing large files locally. It functions like cookies but will allow the web pages to store more information.

Web Workers: Some applications use heavy scripts to perform different functions. Web Workers will not affect the performance of the web page this way as it uses separate threads for processing.
