**Tell us what’s happening:**

For all I know about this challenge, I’m doing this correctly. Just change the arguments of the sum function within the module to a spread operator and run the code. My code passes every test beyond ‘*The sum function uses the … spread operator on the args parameter.*’ Is there a bug with this challenge? It feels like it should be pretty straightforward. Is there a workaround? Should I just wait to finish this challenge until it’s fixed if it is indeed bugged? Or am I actually doing something wrong and don’t see it?

**Your code so far**

```
const sum = (function() {
"use strict";
return function sum(...num) {
const args = [...num];
return args.reduce((a, b) => a + b, 0);
};
})();
console.log(sum(1, 2, 3)); // 6
```
