I am not sure a rust rewrite would be meaningful. Go is great because it's fast to code.It's easy to reimplement typescript in go 1:1 just by looking at the code. Rust on the other hand would take a lot longer to develop. Maybe rust is 20% faster than go but overall the increase from typescript with go is good enough. Maybe rust would yield a 14 times speedup over the 11 times in vscode but go is already good enough…

jokes aside, have you heard of the Jevons Paradox[1]? it feels like the "induced demand" effect to me with the whole "just one more lane" phenomenon you sometimes can see in roadways. when you increase the efficiency of a thing you thereby expand the set of things it can economically be used for, causing an overall increase in total consumption over time - not a decrease like you'd expect from just having made it muc…

the difference is with roads you dont get a lot of good secondary effects, one lane is just like the next. benefits are linear with the cost so they balance out. but with typescript and software in general they can be exponential.

fast type inference unlocks brand new patterns that were too slow to be practical on the old checker. at least some of them will turn out to be useful for peoples projects. and its also great for legacy or less complex code bases that will get faster type checking for free.

I'm still not sold on typescript. I've used it off and on professionally for years and it has always just felt like a maneuver to create a safehaven to C# and java devs scrambling to find roles in the modern landscape. Doing purely functional with it is or at least was an absolute chore and so much extra typing happens for extremely obvious variable values that you could derive from the name of the variable. YES you technically can do functional programming (but as i said its a pain) and YES its optional and you dont have to use it everywhere, but try pulling that maneuver on a technical team "lets use typescript where we each feel like it".

I am still of the opinion that well organized and named JS is all that anyone needs and typescript only exists for fresh graduates and fleeing OOP devs.

I feel like I see all of these debates far less than I used to? Well I don't see anyone arguing about vim and emacs anymore at all, and spaces have mostly won over tabs, and static typing has mostly won over dynamic, with the holdouts being comparative novices and people who program in less modern environments, like in academia and at smaller companies.

Spaces over tabs? Since when?

Remember when people would argue about how types weren't worth the effort? I love TypeScript, if nothing else for how it's been able to popularize types.

I still do argue that for JS. I have yet to see it worth the effort other than making things feel comfortable for former OOP devs coming from other languages.

Are the banks and trading firms that use e.g. Clojure/Elixir/Erlang/Python "comparative novices" or "less modern", whatever that means? These are some of the most sophisticated shops I've ever seen, doing some serious software engineering. I like static types as much as the next person and have written probably more Rust and Scala than anything else, but this seems maybe a bit of a gross generalization.

You probably didn't work on any medium or large codebase and didn't have to do a refactor.

What a nonsense. Perhaps read history of TypeScript and you'll learn why it was created.

the real story here is an incredible team that managed to simultaneously keep two separate codebases alive for the most advanced type system known to mankind (yeahhh yeahh Hindley-Milner eat your heart out). huge congrats to the team! looking forward to the Rust rewrite ;)

Honest question, what do you mean by this?

You really should just not assume things about people with no reason other than "they dont like the things i like so therefor they must not be experienced". I've worked on plenty of very very large codebases with large teams.

> What a nonsense. Perhaps read history of TypeScript and you'll learn why it was created.

did you? it was created by microsoft, a C# shop, to support their existing workflows around typing and hinting support. The typescript creation team was literally led by the guy who made C#.

Algorithm W is like undergrad level of sophistication. People who like HM more (and I am one) don't like it because it's "advanced" and to some extent exactly because it isn't. It's sound and fast and infers almost everything. TS seems to have one of those features now, so that's nice.
