  • 0

Surfing the MDC docs here, I’ve noticed there are quite a few versions of javascript (1.6 to 1.8.5).

I was wondering:

  1. Is there any online reference for Browser / Javascript version supported ?

  2. Is there any practical application for the use of different javascript versions ? According to MDC you need to do something like this to use them:

<script type="application/javascript;version=1.7"/>

Which I haven’t seen in any website IIRC.

Thanks!

    1) Yes, on Wikipedia is a nice list: http://en.wikipedia.org/wiki/JavaScript#Version_history

    2) For websites it’s not a good idea to use newer versions of Javascript, but for plugins for newer browsers it can be helpful. For example, I’m using the forEach function in plugins for Google Chrome
