Add a return type of string when a function is accessed like a variable

Question

I am not sure if this is possible (in fact I\'m struggling to work out what to google for) but here it goes:

I have a function

const test = () => {
           


        

Answer 1

Is it possible to achieve this via Object proxies somehow?

No, this is not possible. You cannot make a callable proxy as a primitive string. If you want your test (function) object to show a custom string when stringified (like when concatenated to an other string), just give it a custom .toString() method:

const test = Object.assign(() => "Hello World", {
  toString() {
    return "123";
  }
});
console.log("Example call " + test());
console.log("Example stringification " + test);
console.log("Function object", test);
console.log("as a string", String(test));
