consider using object destructuring to avoid repetition

[ZooeyMiller]

I'll use your signUpHandler function as an example, you write allTheData.gitterhandle 4 times in this function, and allTheData.password a couple more times.

In order to avoid writing allTheData repeatedly, you can use object destructuring.

You can use this in multiple places in your app to avoid unnecessary repetition.
