I'm pretty new to the web development scene, and I just want to be absolutely clear on this because I've read a few conflicting statements.

I was under the impression that "html5" is a particular way of constructing xml to represent data for a webpage and "javascript" is a programming language that runs as client-side code in the browser. But left and right I see APIs for javascript (workers, geolocation, local storage, etc.) being referred to as an "html5 technology". Wikipedia says that html5 doesn't have a standard yet, so I can't look it up to see if it somehow mandates stuff about javascript.

So will APIs for javascript somehow be apart of the html5 standard? Or has it become a common bad practice to label javascript APIs "html5 technology"?

    Just a technicality - HTML5 does not have to be valid XML, e.g. the <br> tag (without close), is perfectly valid in HTML5, but not in XML. – Daniel B Mar 26 '12 at 6:09
  • HTML5 is a really bad name. In the end it is more about standardizing common existing stuff from web browsers that were not in a standard yet. This ranges from the parsing algorithm for malformed HTML to Javascript APIs to things like video and so on. – hugomg Mar 26 '12 at 13:23
  • The official HTML 5 specification (or 'recommendation') was published by the W3C on 28 October 2014 - Web APIs and scripting are covered in Chapter 6: w3.org/TR/html5/webappapis.html#webappapis – cachvico Jul 9 '15 at 6:03

It's not a standard yet, but you can read the draft specification on the W3 web site. Javascript/Ecmascript is part of section 6.1.6: Events.

  • Javascript is also explicitely mentioned in 6.1.6, "Events", thus making it an integral part of HTML5. – user281377 Mar 26 '12 at 6:09
  • @ammoQ thanks for the correction. I've updated my answer. – Charles E. Grant Mar 26 '12 at 6:51
