I am looking for a full-time job.
Being independent in open source for 3.5+ years has been wonderful. I've gotten done most of the high-level goals I wanted to, and miss having people & structure around me.
If you know of a role for a staff-level TypeScript+web developer, let me know! 🙂

Write flat tests. No "describe", no scenario nesting, no beforeEach/afterEach hooks (as a rule). Each test case is self-contained, listing all the setup it needs. Use Symbol.dispose for reliable cleanup. Use granular test cases.
☝️ These things will make your tests shine.

ECMAScript excitement 😉
TypeScript's @chronicles.org is pitching enum in JS 🎉
It's the good parts of TS enum + enhancements:
🔶 More datatypes: Symbols etc
🔶 Iterable
🔶 Immutable
🔶 Null prototype
🔶 No declaration merging
🔶 Compatible with Node type-stripping 👍
