Benchmark: safeGet comparison (for PR)

Script Preparation code:

var state = {
  wrapped1: {
    wrapped2: {
      location: {
    	search: '',
    	id: 12
      }
    }
  },
  data: {}
};

var safeGet = function(nestedObj, paths, defaultVal) {
  if (!paths || paths.length === 0) return defaultVal
  const result = paths.slice(0).reduce((obj, path, i, arr) => {
    if (!obj) {
      arr.splice(i) // break out of the loop
      return undefined
    }
    return obj[path]
  }, nestedObj)

  if (result === undefined || result === null) {
    return defaultVal
  }

  return result
}
var safeGet2 = function(nestedObj, paths, defaultVal) {
  if (!paths || paths.length === 0) return defaultVal
  for (let p = 0; p < paths.length; p++) {
    nestedObj = nestedObj ? nestedObj[paths[p]] : undefined
  }
  return nestedObj === undefined || nestedObj === null ? defaultVal : nestedObj
}
var safeGet3 = function(nestedObj, paths, defaultVal, p, undef) {
  if (!paths || paths.length === 0) return defaultVal
  for (p = 0; p < paths.length; p++) {
    nestedObj = nestedObj ? nestedObj[paths[p]] : undef
  }
  return nestedObj === undef || nestedObj === null ? defaultVal : nestedObj
}

var dlv = function(obj, key, def, p, undef) {
	key = key.split ? key.split('.') : key;
	for (p = 0; p < key.length; p++) {
		obj = obj ? obj[key[p]] : undef;
	}
	return obj === undef ? def : obj;
