coding style: early exit vs deep nested.

[simpzan]

I like the idea of the project, and wanna join to make a little contribution. before that, I need to understand the code, so I start to read the code.
I found that the coding style of deeply nested if statement is kinda hard to read. I think early exit is much more readable.
Would you consider to make a switch of the style?

Hello @simpzan,

Thank you for your message. It's great you want to contribute and any help would be welcome.

About nesting code style, it adds a lot of readability by adding meaningful blocks. So we won't change it. The only things that could be used to simplifiy is the return callback(err); at the beginning of each callback functions.
