Benchmark: Object Values Filtering

Script Preparation code:

    location: {}
  },
  uuidv4 = () => {
    return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {
      var r = Math.random() * 16 | 0, v = c == 'x' ? r : (r & 0x3 | 0x8);
      return v.toString(16);
    });
  },
  count = 10000

for(let step = 0; step < 1000; step++){
  const
    location = {
      uuid: uuidv4(),
      number: Math.random(),
      number1: Math.random(),
      number2: Math.random(),
      number3: Math.random(),
      number4: Math.random()
    }

  datasets.location[location.uuid] = location
