Just diving into the world of angularJs, I find myself faced with the challenge of upgrading an app from version 0.9 to 1.0.5. The function '$add' called on an array has me stumped. Despite hours of searching through documentation, I still can't figure it out. Can anyone shed some light on this? I'm also curious about the significance and special usage of the '$xxx' keyword within angular.
It seems that the $add function has been deprecated. You can simply substitute it with the built-in Array method push(), as they essentially serve the same purpose.
In reference to the utilization of the symbol $, the angularjs guidelines emphasize:
As a precaution against potential naming conflicts, Angular prefixes names of entities that might clash with $. It is advised not to employ the $ prefix in your code to avoid inadvertent clashes with Angular's functionality.
