Could you tell the difference between these four?
$scope.$watch('foo', fn)$scope.$watch(function() {return $scope.foo}, fn)
$scope.$watch(obj.prop, fn)$scope.$watch(function() {return obj.prop}, fn)

Angular Directive: Click Elsewhere?
Benefit of this solution:
- You only need one bind to
$(document). Other firing of events would depend on the$emitof scope events. - You could use both expressions
click-elsewhere="show=false", andclick-elsewhere="fn()", thanks to$parse.

All Angular Directives That Create Child Scopes
Have this list firmly registered somewhere in the back of your head before embarking on Angular! I can’t tell you how much confusion and pain not realising its existence has caused me. These are the keywords I used to find all the directives that create scope, thanks to @sp00m’s prompt.
Providing that Angular’s documentation is consistent in the way they describe directives, which it seems to be, below is the full list of results, in order of priority level of execution:
Open Sublime From Terminal and Vim
terminal
$ sudo ln -s "/Applications/Sublime Text.app/Contents/SharedSupport/bin/subl" /bin/subl
vimrc
map <silent><leader>os : exe 'silent !subl .'<CR>
Angular Best Practice: Directory Structure
The most important thing is of course to find something that works for you. The other thing is that, as its creator Miško puts it, once you structure it in a particular way, and other people structure it the same way, it makes it easier for you to leap from one project to another.
jQuery Plugin: jquery-transformer
Since I constantly need to use jQuery together with TweenMax and since TweenMax already took care of all the parsing of various types of transformation strings as well as compatibility issues, I wrote a tiny jquery plugin here (more of a wrap up of gsap’s) that could directly access these values like this:
$('#ele').transform('rotationX') // returns 0
$('#ele').transform('x') // returns value of translate-x
Angular Best Practice: Naming Conventions
Summary: UpperCamelCase for Controllers and constructor Services, lowerCamelCase everywhere else.
Non-enumerable Properties
I was trying to figure out a way to enumerate through properties of Math object when I realise that I can’t access any. Whaaat? Why?
