Found out that Safari <4 doesn't support canvas' toDataURL (after using it to implement one of the core functionality of our app). Damn it. about 3 hours ago from web
@tobie Nope. You must be confusing it with `eval` and `arguments` (neither can be Identifiers in assignment/declaration/formal params/catch) about 21 hours ago from Twitterrific in reply to tobie
@diegoperini I think `void+0` looks more confusing. Why not just have `undefined` local variable? It's clear, fast and compresses well. about 21 hours ago from Twitterrific in reply to diegoperini
@ELV1S I hope you're not relying on function decompilation ;) http://bit.ly/Dy9Au 5:41 AM Nov 23rd from Twitterrific in reply to ELV1S
IE's XSS filter can itself be exploited to perform XSS attacks against otherwise safe web sites. http://bit.ly/8iQgNV Great... 6:04 AM Nov 22nd from web
Nice presentation on Javascript performance by @jaffathecake http://bit.ly/17MSZ8 10:21 PM Nov 18th from web
IE9 ditches COM as an object model for host objects... What a relief. 8:43 PM Nov 18th from web
Looks like Opera 10.10 RC3 fixed whatever was affecting Sputniktests and is now leading with score of 176 (http://bit.ly/3yYhfE) 7:21 AM Nov 18th from Twitterrific
@ELV1S `slice` seems to be even faster http://gist.github.com/237930 7:00 AM Nov 18th from Twitterrific in reply to ELV1S
@WebReflection Sure, just not when you compare it to "checked" property of an element ;) 5:27 AM Nov 17th from Twitterrific in reply to WebReflection
Remembered once again that Crockford was right about JS books quality when looking at one in B&N today — http://bit.ly/4AChZW 11:30 PM Nov 16th from web
Apparently `x++` and `x += 1` are NOT functionally identical; former does ToNumber coercion, latter one doesn't. Who would have thought... 3:12 PM Nov 15th from web
Filed few optimizations for Closure Compiler http://bit.ly/4j4U0q. Still need to file a bug with func. expressions turned into declarations. 11:20 PM Nov 14th from web
@miksago Also remember that it's safer to do `Object.prototype.hasOwnProperty.call(obj, prop)`rather than `obj.hasOwnProperty(prop)` 9:59 PM Nov 14th from web
@miksago `hasOwnProperty` is not supported in at least Safari <= 2.0 and IE5. IE5 is pretty much extinct, but Safari 2.0 — not so much... ;) 9:41 PM Nov 14th from web
@jdalton Here are few that you might be missing on mac — http://twitpic.com/pdfg0 10:34 AM Nov 13th from Twitterrific
@jdalton Err... nevermind about Safari 11:04 PM Nov 12th from Twitterrific
@jdalton Still missing Safari 2.x; Also, Opera 10.10b1 is out ;) 11:03 PM Nov 12th from Twitterrific in reply to jdalton
And again, Opera 10.10 spits out some bogus stack trace. This time with: `alert(document.forms.length)` (cc @fearphage, @dstorey) 10:56 PM Nov 12th from Twitterrific
Correct Array#push/pop implementation is not that trivial — http://bit.ly/1GxbhV (many browsers get it wrong too) 6:42 PM Nov 12th from Twitterrific
