In this Hasty Treat, Scott and Wes discuss different error handling strategies.

Cut your time on error resolution from five hours to five minutes. It works with any language and integrates with dozens of other services.

2:07 - Try / Catch

This can be done at call time or inside the function

4:10 - Higher Order Function

Makes a function that returns a new function which in turn calls your original function (but with a .catch chained on)

7:46 - Handle the error when you call it

Use async/await but chain a .catch onto the end

9:03 - Node.js Unhandled Rejection Event

process.on('unhandledRejectionEvent', callback)

9:40 - What do do with those errors

Send to error tracking service
Possible to give the user a reference number
