EcmaScript5 features

Question

I have a fair knowledge of ES3, but I'm not really up to date about the features of ES5. I - more or less - know about:

• Object.create(), Object.freeze()
• "use strict"
• getters and setters
• the methods map(), filter(), every(), some() of Array.prototype
• JSON.parse()

but I'm sure I am missing other goodies. Moreover, I do not know all the details about the above: for instance I am not sure about all the effects of "use strict".

Is there a good resource where to learn all the ins and outs of ES5, in particular constrsting it to ES3, short of reading the final final final final draft?

Answer 1

Check out the Compliance table

Then just search for each feature on the MDN.

There also seems to be a page at Mozilla
