It is for me. If someone says TypeScript is faster than X, they rarely mean the build time. I understand other people's points about TypeScript not being a runtime at all and only being a compiler, but when casually saying "TypeScript is faster than say ruby", people do not mean the compiler.

But no one actually says "TypeScript is faster than say ruby". They probably say "node is faster than say ruby" or maybe "bun is faster than say ruby". Perhaps they say "JavaScript is faster than say ruby", although even that is underspecified.

Then read the article? I don't get it - Typescript, to anyone familiar, is not a language runtime. It does not optimize. It is a transpiler. If you don't even know this much about Typescript, you aren't the audience and lack prerequisite knowledge. Go read anything on the topic.

If someone posted an article talking about the "handedness" of DNA or something, I wouldn't complain "oh, you confused me, I thought you were saying DNA has hands!"

well, thanks for explaining. we might just simply disagree here. when I hear "TypeScript" I think of TypeScript, and when I hear "JavaScript" I think of JavaScript. I know what you mean re: casually speaking, but this is a blogpost from the TypeScript team. That context is there, too. I think if the same title were from an AWS release note, I'd totally see what you mean.

Typescript is JavaScript at runtime. It’s not a separate language, just like Python with type annotations (TypePython?) is just Python at runtime. Both are just type annotations that get stripped away before anything tries to run the code. That’s the genius of the idea and why it’s so easily adopted.

That’d be the autism kicking in, you’re gonna have to be 10% less miserable if you want anyone to put up with you.
