Inquiry about "Use the Rest Operator with Function Parameters"

JavaScript

Tell us what’s happening:

Is that correct? I got 0 in the console, but the exercise doesn’t accept that solution.
My code so far


const sum = (function() {
  "use strict";
  return function sum(...args) {
    const result = [...args];
    const reducer = (acc, props) => acc + props 
    return result.length === 0 ?   "0" : result.reduce(reducer);

  };
})();
console.log(sum()); // 0

This check is not needed, it will also mess with the tests, you should leave it as it was

Here you are doing twice the same thing, creating result is unnecessary and can make you not pass. Just use args

I see, thank you.

const sum = (function() {
  "use strict";
  return function sum(...args) {
    const result = [...args];
    return result.reduce((a, b) => a + b, 0);
  };
})();
console.log(sum()); // 0
