Typo in the title (should be "Compiler" and not "Complier")

"You have 20 seconds to compile."

No this is typescript. They meant what they said. ;)

Does Typescript even compile or is it transpile?

[WorldMaker]

Both. Type erasure is a transpilation process. Generating .d.ts and other type metadata files is a compilation process. (With conditional types alone the type checker is compiling a fully Turing complete mini-language.)
