State of ECMAScript Implementations
Category: JavaScript
John Resig has done some research on the state of ECMAScript 4 implementations:
I’ve just completed my first survey of the current ECMAScript 4 implementations. I went through and attempted to compile as many bugs and features as possible, as stated by the ECMAScript 4 specification and double-check them against all the actively-maintained implementations. You can view a nice overview below.
I think it’s fascinating to note that there’s 3 implementations that already have over 25% of all the new features in the language implemented.
And, there is an interesting note on Tamarin:
Might be worth mentioning that the Tamarin VM by itself doesn’t directly support ECMAScript source code. Rather, the subproject esc (written in ECMAScript 4) compiles ECMAScript 4 to abc bytecode that is run by the Tamarin VM. (And I imagine you know that already, but it might be an interesting detail for some visitors.)
I’m not holding my breath to see IE on that chart anytime soon :D
