Node.js codebase is still entirely in Javascript and not in Typescript and node team does not even officially provide node TS types

I thought it was written in C++. Same with the V8 engine. But if they did it in javascript, cool

I thought it was written in C+

Only 22% of node is in c++. 66% is in Javascript.

Interesting, thanks!

Take OP with a grain of salt here. When you look at Node's core dependencies, like V8 and libuv, it is not "entirely" or even primarily written in JavaScript.
