Preparation code

Preparation code HTML (this will be inserted in the <body> of a valid HTML5 document in standards mode) (useful when testing DOM operations or including libraries)

Include JavaScript libraries as follows: <script src="//cdn.ext/library.js"></script>

Define setup for all tests (variables, functions, arrays or other objects that will be used in the tests) (runs before each clocked test loop, outside of the timed code region) (e.g. define local test variables, reset global variables, clear canvas, etc.) (see FAQ)

var obj = {
  a: 1,
  b: 2,
  c: 3,
  d: 4,
  f: 5
},
hasOwnProperty = Object.prototype.hasOwnProperty,
keys = Object.keys(obj);

function forInIf(obj) { 
  var key, value;
  for (key in obj) {
    if (hasOwnProperty.call(obj, key)) {
      value = obj[key];
    }
  }
}

function forInNotHasTrue(obj) { 
  var key, value;
  for (key in obj) {
    if (!hasOwnProperty.call(obj, key)) { 
      continue;
    } else {
      value = obj[key];
    }
  }
}

function objectKeysForEach(obj) { 
  Object.keys(obj).forEach(withKey);
}

function keysForEach(keys) { 
  keys.forEach(withKey);
}

function forLoop(obj) { 
  var key, value;
  for (var keys = Object.keys(obj), i = 0, j = keys.length; i < j; i++) {
    key = keys[i];
    value = obj[key];
  }
}

function each(obj, fn) {
  var key;
  for (key in obj) {
    if (hasOwnProperty.call(obj, key)){
      fn.call(obj, obj[key])
    }
  }
}

function forInIfEquals(obj) {
  var key, value;
  for (key in obj) {
    if (hasOwnProperty.call(obj, key) === true) {
      value = obj[key];
    }
  }
}

function forInHasNotTrue(obj) { 
  for (key in obj) {
    if (hasOwnProperty.call(obj, key) !== true) { 
      continue;
    } else {
      value = obj[key];
    }
  }
}

Title

Async (check if this is an asynchronous test)

Code

forInHasNotTrue(obj);
