Where can I check when was a specific javascript object or method introduced to all major browsers?
E.g. I just though I had a horrible production bug for a week because the Safari I just downloaded fails on JSON.stringify(), but then discovered I had somehow download an ancient Safari version, and the latest Safari versions do support it. Where can I find when exactly开发者_如何转开发 did Safari add JSON.stringify()?
Bonus: This is how I got lured into download a Safari version from three years ago. WTF?
http://caniuse.com is also a great source of such information.
Well there's http://www.quirksmode.com
(Much more general but covering many more browsers is http://en.wikipedia.org/wiki/Comparison_of_web_browsers#Browser_features)
