How should this #typescript issue be properly titled? I (clearly) have trouble describing the problem:

Today I learned that if you don't want to emit internal types from a library, you can set `stripInternal` to true in TypeScript config and add a `@ internal` comment:

Let's have fun today and think how we can pass the type to generic type in TypeScript later

I was going to tweet about this, but you beat me to it! Nice to finally have this working.

I thought this was a tremendous sign... And I was right! github.com/microsoft/TypeScr…
@typescript now has indirect type narrowing via const thanks to @ahejlsberg ❤️🌻

One small quality of life improvement for frontend devs in TypeScript 4.3: you can now jump into imported files TypeScript doesn’t understand, like CSS.

Oh well, actually the time was "now" for almost a year - this PR was originally submitted more than a year ago 🤣

This is actually _really good_ and there are times when defining your types in terms of an existing value is the 100% best thing you can do 1/
Not sure if I'm proud of ashamed of this, but I set out to generate a restricted type based on existing data... and it worked?

Do you remember the difference between unknown and any in #typescript?
🥇 You can assign anything to unknown and any.
🥈 You can't assign unknow to anything except of unknow and any.
🥉 You can't access unknow properties (unlike any).

Especially useful if you use TypeScript to develop a GitHub Action:

Lately, I started digging deep into @github Actions. The way how most actions end up placing build artifacts on the default branch was driving me mad. In this article, I explain how we can use GitHub Actions to develop GitHub Actions and fix it!

Yesterday I shrank a TypeScript declaration from 700KB to 7KB by changing one line of code 🔥

By default, TypeScript WON'T throw compilation errors on unreachable code 😱
You might want to tweak that! Just set `"allowUnreachableCode": false` in tsconfig.json

Tip: make sure your declaration files are type-checked.
Compile-time errors in unchecked *d.ts files can hide real bugs and lead to painful debugging sessions.

Use auxiliary package.json to avoid "deep" import paths to your npm packages. This is a great solution if you want to clearly divine public/internal interface of your project.
