In addition to the responses from the Mozilla guys, I'll also point out that the limiting factor in speed for most web applications is not javascript runtime speed but dom manipulation, reflow, and repaint. The tricks for optimizing these t

The problem with answering this question is what exact subset of Vim features you use and whether you're willing to learn replacement commands or hack your missing features in. Of the features you list, you can record macros into a buffer (

You do feature based branches that get rebased against master on a regular basis and push -f your dev branch in the evening so your changes are backed up. When two devs are working on the same branch they coordinate via chat who (or whoever

If you're considering this, be aware that writing JS that takes advantage of new JS language features in v8 and not present in IE/Rhino is not considered bad form in the node.js community. Also, Rhino is ~50x slower than v8, which doesn't s
