Preparation code

Benchmark.prototype.setup = function() {
    var chunk_data = [],
        split_data, slice = '12345';
   
    for (var i = 0; i < 2000; i++){
        chunk_data.push(slice);
    }
   
    split_data = chunk_data.join(',');
    chunk_data = chunk_data.join('');
   
    function use_split() {
      split_data.split(',');
    }
   
    function use_match() {
      chunk_data.match(/[\s\S]{1,5}/g);
