title: Which is more Efficient array.forEach or angular.forEach?
body: <h2>array.prototype.forEach</h2>
  
  <p><code>forEach()</code> executes the provided callback once for each element present in the array in ascending order. It is not invoked for index properties that have been deleted or are uninitialized (i.e. on sparse arrays).</p>

  <h2>angular.forEach</h2>
  
  <p>Invokes the iterator function once for each item in obj collection, which can be either an object or an array. The iterator function is invoked with iterator(value, key, obj), where value is the value of an object property or an array element, key is the object property key or array element index and obj is the obj itself. Specifying a context for the function is optional.</p>

  <p>But I want to know which one is more efficient and the performance.</p>
