'Build' is commonly used both ways, and not just in software.

But the article is very clear about what it means by "build". The three places that it uses the term wrt software, in context, are:

> would you rather have TypeScript build your code 20% faster?

> did this make my build faster?

> You might be surprised what's making it into your build!

which are clearly talking about the build process and inputs, not its output.

That interpretation doesn’t even make sense in TypeScript though, does it? You don’t build a “TypeScript app bundle” and send it off to be installed on your TypeScript executor. The only interpretations I can think of for “TypeScript build” would be 1) the typechecking process, which just outputs a list of type errors and warnings or 2) the transpilation process which strips out all the TypeScript syntax from your code leaving you with valid JavaScript.
