I use stackoverflow to understand the fundamentals of handling regular expressions in javascript. But I couldn't find the site that deals with the implementation of javascript.
Concerning CSS I have already asked questions on this site: [compositing-1][compositing-2]I am looking for a concrete example of the application of the simple alpha blending formula · Issue #517 · w3c/fxtf-drafts · GitHub
but where can you find the equivalent site for javascript?
The official Javascript documentation is the ECMAScript specification. The current draft is here, and the latest Ecma-approved edition is here. (Not sure if that's really what you're looking for, though.)
that's exactly what i was looking for
