Code does not compile.
You did not handle any errors and this will crash in a lot of places.
Please format your code properly like surrounding code. 80 chars per line, 2 spaces to indent, inline {} braces, etc...

Will do a real review after basics are addressed.

a lot of these new comments are unnecessary... please delete them

You need to handle errors in parseJson() or else this code will crash.

Some comments were not properly addressed and formatting is still all over the place.

Please do not re-throw an error... it is not caught. It will crash the program.
