babel-plugin-transform-catch

Motivation

catch in Google apps script is reserved word and this make it impossible to use with promises. And while you can easily overcome it by not using promises which in fact absent in GAS environment the problem become hard to solve if your project requires 3rd-party library. In example jsonwebtoken, which dependent on another library, which has .catch in its code.

At the end of the day it become simpler to roll-out babel transformation than any other option.
