Just found this comment in some code I wrote a few months ago... don't think I've ever been more honest!

Isn't .catch() for errors, not .then()?

thought the first parameter of then is for success and the second for error callbacks, or .catch()

@internerd no clue truthfully. It's calling some third party library and this was probably re-typed from some example in the code. Since I have never caught an error I have no idea if it works!

*an error

Now you're good! Ship it!

@kurtr chaining then() requires the previous then() to return a promise. In this case all then()'s will be called, you should be using catch().
Alternatively you can include two params in the first then() for resolve() and reject().
