Some things that I found interesting:
Compile-to-JavaScript pretty much just means CoffeeScript.
- CoffeeScript 590 64%
- TypeScript 181 19%
- ClojureScript 38 4%
- Dart 38 4%
- Other 82 9%
The "No semicolon" movement is very much a minority.
"Methods with one space - method: function() {" is much more popular than "Methods with two spaces - method: function () {". I adopted two spaces because I thought it was a stylistic best practice, but it's apparently not a style that many follow. I'll probably switch to one space.
Only 25% say "Yes", they write tests. This is bad, but I think it's a number that will grow as people take JavaScript seriously and the community matures.
AMD is still the clear winner, but I'm hoping to see that shift to CommonJS-style modules over time. :-)
Grunt dominates all.
Angular JS is huge! I had no idea how widely adopted it was. I need to set my "They're getting the markup all messy with behavior!" pickiness aside and give it another try one of there days.
