I wanted to easily make HTTP requests (both GET & POST) with a simple interface that returns promises.
The popular request & request-promises package are good, but I wanted to figure out how to do it w/out using external dependencies.
The key features are:
| /** | |
| * Remove all specified keys from an object, no matter how deep they are. | |
| * The removal is done in place, so run it on a copy if you don't want to modify the original object. | |
| * This function has no limit so circular objects will probably crash the browser | |
| * | |
| * @param obj The object from where you want to remove the keys | |
| * @param keys An array of property names (strings) to remove | |

| var fd = form || new FormData(); | |
| var formKey; | |
| for(var property in obj) { | |
