…e jQuery namespace.
The coffescripts were compiling with a global use of the $ shortcut which can conflict with other libraries that could be included in an application. By assigning the $ = jQuery, a var will be defined scoped to the function generated by compiling the coffee scripts. This will allow for the functions to use $ internally as jQuery.
For example, if prototype is included, this avoids the two following errors on initialization of the page:
editable_form.js?body=1:5 Uncaught TypeError: Cannot read property 'editableform' of undefined
at editable_form.js?body=1:5
at editable_form.js?body=1:55
and
error_handling.js?body=1:2 Uncaught TypeError: Cannot read property 'editable' of undefined
at error_handling.js?body=1:2
at error_handling.js?body=1:9
