Benchmark: Get props - MeasureThat.net

Script Preparation code:

var obj = {
  a: { b: { c: 'CCC' } }
};

function get(obj, path) {
  var parts = path.split('.');
  var property = Object.assign({}, obj);

  for (var i = 0; i < parts.length; i++ ) {
    property = property[parts[i]];

    if (!property) {
      property = undefined;
      break;
    }
  }

  return property;
}

function switchCase(obj) {
  var res;

  Object.keys(obj).forEach((key1) => {
    switch(key1) {
      case 'a':
        Object.keys(obj[key1]).forEach((key2) => {
          switch(key2) {
            case 'b':
              Object.keys(obj[key1][key2]).forEach((key3) => {
                switch(key3) {
                  case 'c':
                  res = obj[key1][key2][key3];
                  break;
