Currently the keys of the entries returned by `Set.prototype.entries()` are the same as the values:
```js let set = new Set(['a', 'b']); let pairs = [...set.entries()]; console.log(JSON.stringify(pairs)); // [["a","a"],["b","b”]] ``` Given that sets are ordered, I’d use the “position” of an entry as the key: [[0,"a"],[1,"b”]] Rationale: First, having an indices as keys makes the entries more useful. Second, destructuring already treats entries as if they had indices: ```js let [x,y] = set; // x='a'; y='b’; ``` -- Dr. Axel Rauschmayer [email protected] rauschma.de
