Typescript doesn't like my variable name "⛄" and I can't suppress the error

Question

I am trying to write a server and I keeping typescript error that I cannot supress:

As you can see I already try to use ts-ignore but it does not supress the error, what am I doing wrong?

Here is my code:

// @ts-ignore
const ⛄ = (fn) => {
  return (req, res, next) => {
    return fn(req, res, next).catch((err) => {
      return next(err);
    });
  };
};

EDIT: Yes, this Unicode is valid Javascript variable name: EDIT 2: Apparently ⛄ is not valid, alrighty then.

It's not a TS error, it's a JS syntax error, so you can't ignore it. — John Montgomery, Jul 24 '19 at 21:02
Are you sure this is a valid js identifier? If so I'd report a bug. I remember a recent bug about strange characters in variables — Titian Cernicova-Dragomir, Jul 24 '19 at 21:02
@TitianCernicova-Dragomir Yes, this is valid Javascript name, I am not getting a Javascript error, I am getting a Typescript error. — Bill Software Engineer, Jul 24 '19 at 21:06
@Bill I just tried it right now and got "SyntaxError: illegal character" — John Montgomery, Jul 24 '19 at 21:07

According to the JavaScript variable name validator it's an invalid identifier:

If you still think it should be valid, then maybe a defect report is the next step.

"That’s an invalid identifier according to ECMAScript 6 / Unicode 8.0.0."

You are getting a javascript error, not a typescript one.

Also.. I don't think naming variables with emojis is good coding practice.
