- 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)

- 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
