    React 18 and the future of async data

    Friend, I have glimpsed the future and it is amazing. React 18 is shipping with <Suspense> and startTransition for deferred component rendering, but not data loading. That's coming in a future 18.x version.

    A better React 18 startTransition demo

    Demoing startTransition is hard. Modern computers are too fast 😅 – Dan Abramov, a React core team member, helped me fix it up. Here's what I learned

    How React Query gives you almost everything you thought you needed GraphQL for

    GraphQL solves every problem you've ever had talking to APIs on the frontend. Mention a switch to GraphQL to your team and they think it's a joke. Rewrite our entire app? oh you jokester. React Query is the perfect middle ground ❤️

    In 2020's, what is "frontend"? 🤨

    "He's a frontend guy, is this even a fair question to ask?" The head of engineering was worried about our systems design question …

    The Big Mac index and Jest fetch testing

    The Big Mac index is a purchasing power parity index published by The Economist. Jest fetch testing is a tech task so frustrating that it almost made me quit the industry. I'm writing this so you don't have to read 8234721 different blog posts, stack overflow answers, and GitHub threads with conflicting info on how to get Jest and fetch to play together.

    Just for fun 👉 React vs. jQuery vs. Svelte, same 🐱 app

    I was bored Monday night and decided to see if I still know how to build with jQuery. Nothing better to do, no pressing ideas, a bit of fun. Also a favor for a friend who's preparing to talk about React to a bunch of people who've never seen it before 😛

    Counting web sessions with JavaScript

    How many touch points does your sales process require? Do you need 2 ad clicks or 5? Two shiny demos or one fat video? As an engineer, you might not care, but this is the stuff that keeps your CEO and growth lead and head of product up at night. A business owner that can answer that 👆 question reliably is god.

    Javascript debugging [slightly] beyond console.log

    My favourite tool for javascript debugging is `console.log`. I mean, I love `console.log`. If I ever get a programming tattoo, it's going to be `console.log` or some variation thereof. Simple to use, works every time, and every programming language I've used since I was 9 has had some variation of it.
