Guy builds something he likes and shares it with the community:
Normal people:
"Oh this is cool I think I'll try it"
Linux community:
Ego hurt, complains it's not Arch enough, whines about download size and bloat
Governor Cox:
Let's bad policies to encourage people to move to Utah even though we don't have the infrastructure to support it.
Also Governor Cox:
Oops we don't have the infrastructure to support this many people. Time for some really bad top down housing policies!
"Cracked" developers are really just people with a high coding IQ.
Cracked Devs > Senior Conventional Devs
Finding cracked developers is hard because only a cracked developer can identify another cracked developer.
Spent a couple of hours today getting typescript to play nice with hmr without losing type information in a monorepo. Typescript is my passion
I want whatever you're smoking if you think that Skia gets even close to RN in native performance and feel. Skia is genuinely the worst looking, worst performing rendering engine that I've ever had the displeasure of using
thats why #Flutter is better than #ReactNative
1) Flutter renders its own UI with Skia -> same look & feel on iOS & Android
2) RN still depends on native views & JS native sync
3) Flutter’s toolchain = one stack (Dart + DevTools)
RN = Metro + Xcode + Gradle + Pods + config
Some of my favorite directives:
"use client"
"use server"
"use workflow"
"use react"
"use ligma"
"use cache"
"use cache:remote"
"use tanstack"
"use 67"
"use types"
"use context"
"use props"
"use jsx"
"use eslint"
"use prettier"
"use ai"
"use timezones:local"
"use php"
"use rsc"

You're a JavaScript dev. You just pushed a new feature to production.
An hour later, the Slack messages start.
TypeError: Cannot read properties of undefined (reading 'name')
Your stomach drops. You passed the wrong prop. Or an API response changed slightly. Or you misspelled 'user.firstName' as 'user.fName'. And your entire app crashed for 10,000 users.
This is the exact moment 90% of JS devs just accept that "this is fine."
For months, I avoided TypeScript. I thought it was for enterprise nerds who missed Java. I loved the "freedom" and speed of JS. I thought, "I'm a good dev, I can just be careful."
I was wrong. I was just learning about TypeScript, and the "aha!" moment hit me hard.
I was expecting a chore. What I got was a superpower.
Here was my journey from skeptic to believer.
Level 1: The Editor Gets a Brain
I used to 'console.log(props)' just to remember what was in it.
- My new workflow: I define an 'interface User { ... }'.
Now, in my component, I type 'props.user.' and VS Code instantly shows me a list of 'firstName', 'lastName', and 'email'.
It's not just autocomplete. It's my editor becoming a co-pilot that knows my entire codebase.
Level 2: The End of "Oops" (The "Contract")
I used to write 'function greet(user) { ... }' and then accidentally pass 'greet("Harsh")'. It breaks at runtime, when the user clicks the button.
- My new workflow: I write 'function greet(user: User) { ... }'.
I try to pass it a string. A fat red squiggly line appears.
I just fixed a production bug before I even saved the file. This isn't boilerplate. This is a contract that protects me from myself.
Level 3: The "Wait, what?" Features
- Teamwork: The backend team changes an API response. They don't just "tell me on Slack." They update the shared 'types' file. The second I pull from git, my editor tells me exactly what broke.
- New Devs: A new dev joins. I don't spend 3 days explaining our data. I just point them to the 'types' folder. They're productive on day one.
Level 4: The "God-Mode Refactor" (This is what sold me)
This is the real magic.
- My Problem: I need to rename 'user.email' to 'user.emailAddress' across a 50,000-line codebase.
- My old workflow: "Find & Replace." Close my eyes. Pray.
- My new workflow:
1. I go to my one 'User' interface.
2. I rename 'email' to 'emailAddress'.
3. My entire codebase instantly lights up with red squiggles.
It's not a list of errors. It’s a perfect, automated to-do list of every single file I need to fix. I can refactor a massive app with 100% confidence.
I thought TypeScript was a cage. It's not. It's a suit of armor. It lets you move faster and safer because you're no longer afraid of breaking things.
