Hi, im glad you have an interest in this project.

Could you change your editor settings so the function and their parameters have no space in between for the diff to be readable?

var foo = bar(one, two) {
  ...
}

I would also like a short description of the changes you are doing.

@aksee I am still waiting for your reply. I will close the PR if I dont hear from you in the next 2 weeks.
