export default function () {
- var i=0, tmp, x, str='';

if (x = toVal(tmp)) {
str && (str += ' ');
str += x
}
}
}
return str;
}Benchmark on only string concatenation shows an increase of about 1,000,000 operation/sec.
Note: I got benchmark results only in node, in a really inaccurate way. but theoretically, it must increase the performance.
