I just had to shout out [YellowAfterlife](https://twitter.com/yellowafterlife)’s awesome tool - [json2typedef](https://yal.cc/r/19/json2typedef/) ([github code](https://github.com/YellowAfterlife/json2typedef)). Paste in a JSON blob (and click out) and it generates a typedef.

This is a handy time saver when creating type definitions for libraries from their API documentation / examples.
