Most of the snippets fall into either column 5 or 10 in the output table on this site[1] (which is down, hence cached copy, hopefully it works for you guys). These are mostly interoperable across browser.

A number of the examples can be boiled down to the following test: if (false) { function x(){ console.log('worked'); } } x(); In Chrome, IE, Opera, and Safari 'worked' will be logged. In Firefox it will silently fail.

I haven't looked in detail at all of Brian's snippets. But several that I have glanced at look to me like they wouldn't be interoperable among current browsers. _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
