Benchmark: isEmpty (forIn vs Object.keys vs Object.values vs lodash.isEmpty)

HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

window.emptyArray = [];
window.emptyObject = {};
window.emptyString = '';
window.filledArray = [];
window.filledObject = {};
window.filledString = '';

Array.from((Array(100).keys()))
  .forEach((result, i) => {
    filledArray.push(0);
    filledObject[i] = 0;
    filledString[i] += '0';
  });

window.forIn = source => {
  for(var prop in source) {
    return false;
  }
  
  return true;
};
window.lodash = _.isEmpty;
window.objectKeys = source => Object.keys(source).length === 0;
window.objectValues = source => Object.values(source).length === 0;

Tests:

forIn
forIn(emptyArray); forIn(emptyObject); forIn(emptyString); forIn(filledArray); forIn(filledObject); forIn(filledString);
lodash
lodash(emptyArray); lodash(emptyObject); lodash(emptyString); lodash(filledArray); lodash(filledObject); lodash(filledString);
objectKeys
objectKeys(emptyArray); objectKeys(emptyObject); objectKeys(emptyString); objectKeys(filledArray); objectKeys(filledObject); objectKeys(filledString);
objectValues
objectValues(emptyArray); objectValues(emptyObject); objectValues(emptyString); objectValues(filledArray); objectValues(filledObject); objectValues(filledString);
