Why doesn't VSCode see the variable's type?

Question

JavaScript

VSCode sees the type of the class and the return type of the constructor, but does not see the type of the variable... why is that?

Answer 1

Because the repl variable must have an explicit type. perhaps it:
const repl: Type = new REPL.REPLServer();
const repl: REPLServer = new REPL.REPLServer();
