Script Preparation code:

var availableSizes = [];
for(var i=0;i<10000;i++){
  availableSizes.push({label: i, system: i});
}

Tests:

JSON.stringify
var output=[]; for(var i=0, len=availableSizes.length; i<len; i++){ output.push(JSON.stringify(availableSizes[i])); }
String concat
var output=[], SUPER_DELIM = ' }~\t|{ '; for(var i=0, len=availableSizes.length; i<len; i++){ output.push(availableSizes[i].label + SUPER_DELIM + availableSizes[i].system); }
