I'm converting the "famous" CreatePlane script to javascript! Only 3 errors left!

After a good bit of "ctrl + h", "ctrl + c and v", I've only got three errors left!

1: Assets/Editor/PlaneCreator/CustomPlaneScript.js(108,17): BCE0043: Unexpected token: default.
2: Assets/Editor/PlaneCreator/CustomPlaneScript.js(115,9): BCE0044: expecting }, found 'plane'.
2. Assets/Editor/PlaneCreator/CustomPlaneScript.js(204,5): BCE0044: expecting EOF, found '}'.
