Article - Optics in typescript
Article - Introduction to composable optics

repo - openapi refinements
repo - monocle-ts programming examples

Based on the ksaaskil repo above, I made this simple exercise in codesandbox. I hope it could prove useful for someone completely new to lenses and optionals:
