TypeScript is Literal Magic

Love love love it ❤

Reinvented the class

That’s actually insanely cool

How to get all these items in dropdown liat

ClojureScript still wins

Imagine if this existed in css, lot of libraries would see their last days

Useless

There was only one time I really applied this feature, love typescript

Wooooo

Why?

👏👏👏👏

I dont really like the way they implemented template types.
It's not possible to make a hex color type (`#${"a" | "b" | ... | "z" | "A" | ... | "Z" | 0 | ... | 9}`), because it would be to many possible combinations. They either could have just checked, if the input matches the template instead of generating and saving every possible combination and so limitating the range of possiblities, or, what would be even better, implemented regex based template types.

Something that I also miss in ts, are conditional Interface fields.
To always use
type T = {
a: true;
b: number;
} | {
a: false;
}
really sucks.
I would really like something like this.
interface I {
a: boolean;
b[a]: number;
}

cool

Lol, I just did this like 2 days ago except manually

SO MAGICAL 🤩

Wow... Now that is a lovely type system! Gets me more interested in picking up Typescript for sure!

You always make confused explaination

I'm creating a card game with different colors and values. This literally saves my life. 7 Lines of code result in 105 unique cards.

Literally magic.

So... they have limited your ability to use whatever whenever, but then have added a way around it? I've will never understand why TypeScript exists.

This might be the most glorious thing I’ve witnessed all week

Jesus JavaScript Is such a mess

I lost my last braincell trying to be a programmer now i dont know what 1 + 1 in math anymore

JS the world

Why not just use an array?

Really useful 🤠

😳👍👍

You did it, you implemented elm in ts

How are you adding emoji?

Meanwhile in JS u don’t even need to worry about types, but thanks.

Those are like inline enums

Instead of arrogantly bragging about Template Haskell, I'm going to try implementing a similar process to what was shown to determine ease or difficulty

You can't have a language called "TypeScript" without it involving a little type theory.

So this is C++ Enum with emojis?

What the fuck is a type

Nice, now I can make my code completely incomprehensible and ensure my continued employment. After all, no one they hire will be able to decipher the ultra-nested hell I use this feature to create in my codebase.

I don’t understand this sorry

Could you do a video about types and interfaces. And when to use what. The seem to partially be redundant.

Wait till typescript devs learn what a struct is

TypeScript is actually unnecessary trash bloat tho, change my mind ¯\_(ツ)_/¯

Didn’t understand any of this, thanks

How to derive an array of these 25 types. Or do I need to do it the hard way?

Are these equivalent to c# enums?

Wow, almost looks like an algebraic data type. I have never seen anything like that, yet I see that again

That looks very cool

How do I save this

No

I love ts

Very interesting
