If you become exceptional at managing agents, but are also exceptional in your understanding of the fundamentals, you will be unstoppable.

We all prefer to work with masters of their craft. What’s new: you can’t afford to miss out on the amplification agents have on your output

When interviewing for a new role, grill the hiring manager on what excellence looks like.

If they can’t paint a vivid picture of what it takes to win, run as fast as you can.

ElementRef is so freaking useful for finding the right types for useRef in React.

[Tanner Linsley @tannerlinsley]

Short-term thinking: We don't have time to write tests.

Long-term thinking: Tests will save us time.

With tests, we can:
✅ Understand how each feature is supposed to work
✅ Automate redundant checks during development
✅ Know immediately when we make a mistake
✅ Change code with confidence

"can we connect on a call"

I recommend creating a minimal repro ...

Our backend refactor keeps getting backlogged. It's non-sense!"

- A Software Developer told me last week

Well... The PM's job is to help increase the company's revenue, indeed!

[Matt Pocock @mattpocockuk]

Since React 18 and TypeScript 5.1, React.FC is fine to use again.

- No more implicit 'children' prop
- No more errors returning number, string, undefined

It's still not my number one recommendation, but I've stopped hating it.
