Turn a function into an inline web worker

create-worker.js

(function(){
  var Blob = this.Blob;
  var URL = this.URL;
  var Worker = this.Worker;

  this.createWorker = function(src){
    src = src.toString();
    var srcLines = src.split('\n');
    // Remove the outer function. There's probably a better way.
    if( /^f.+\{/.test(srcLines[0]) ){
      srcLines.shift();
    }
    if( /\}/.test(srcLines[srcLines.length - 1]) ){
      srcLines.pop();
    }
    
    var blob = new Blob([ srcLines.join('\n') ], { type: "application/javascript" });
    var blobUrl = URL.createObjectURL(blob);
    var worker = new Worker( blobUrl );
        
    return worker;
  };
