given an iterator, what's the best way to create an Array?
for example,
let map = new Map(); map.set( 'key1', 'data' ); map.set( 'key2', 'more data' ); ... // now, wish to have an array of keys let arr = //??// map.keys() //??//
I could do something lame like
function iter2array( iter ) {
let arr = new Array();
for( let e in iter ) arr.push(e);
return arr;
}
but there has to be a better way.
