HTML5 used to have a lot of functionality that had to be implemented by javascript, but now you can use the tag attribute of the HTML5 element. Because of the large number of javascript attributes that can be replaced by HTML5 on web pages, the language becomes easy to understand, and only html4 needs to cooperate with javascript to do so.

New elements

HTML5 adds canvas elements (painting), video elements (media playback), audio elements, new special content elements (article, footer, header, nav, section), form controls (calendar, date, time, email, url, search).
