I'm trying to figure out the most painless way, given a set, to return the set's values as an array. Possibilities: 1. harmony wiki (http://wiki.ecmascript.org/doku.php?id=harmony:iterators) suggests the following, but it is a syntax error in traceur, continuum and "node --harmony" ```js let arr = [e for e of mySet]; ``` 2. The ES6 standard supports the following production (i.e. expression, not var, before 'for'): ``` *IterationStatement : for ( LeftHandSideExpression of AssignmentExpression) Statement* ``` (see http://people.mozilla.org/~jorendorff/es6-draft.html#sec-13.6.4.2) which suggests I should be able to do this: ```js let arr = []; for (arr[arr.length-1] of mySet); ``` (I can do the equivalent with for-in) but that also errors in the above three transpilers 3. So then I'm left with the pedestrian: ```js let arr = []; for (e of mySet) { arr.push(e); } ``` 4. I also wondered if `Array.from(mySet)` would do the trick but again doesn't seem to pass muster with any of the above transpilers. (continuum returns a zero length array and the other two don't know Array.from) Wondering if I'm missing something better.
