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&s=iterator) suggests the following, but it is a syntax error in traceur, continuum and "node --harmony" 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: 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: 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. thanks Angus @angustweets
