Echo JS 0.11.0

... and the same in stratified javascript:

var seq = require('sjs:sequence');
var dataSet = ['This', 'is', 'how', 'we', 'do', 'it'];

var lyrics = dataSet ..
  seq.map.par(3, function(x) {
                   hold(Math.floor(Math.random()*1000)+1);
                   return x + '♪';
                 });

console.log('Finished processing all the data');
console.log(lyrics);
