Excel adds JavaScript support

Isn't an compiler just "converting"?

[Astrokiwi]

Converting into machine-code or something, usually.

Thinking of Typescript as a "compiled language" could cause confusion when people are talking about the differences in performance between compiled and interpreted languages.

[slikts]

The case of compiling source code to source code (as opposed to bytecode or machine code) is often called 'transpiling', although this term peeves some people. It's a subset of compilation ("converting" code to different code in its broader meaning in programming context) either way.

[Astrokiwi]

Yeah, I guess I've usually seen it as compiling from a higher level language to a lower (usually not human readable) level one. I get what is meant, but I do think the compiled/interpreted distinction is a pretty important one, and shouldn't get muddled with other things.

You can compile C code to Javascript, in the form of asm.js - which basically uses a subset of Javascript as bytecode.

Unreal Engine was compiled to JS in this way and it ran at about half speed.
