title: using lodash instead of angular.forEach for array of arrays
body: <p>Here is my example array</p>
  
  <pre><code>var studentId= 2;
  var students = [
  [{id:1,C:40,PHP:50},{id:2,C:60,PHP:70},{id:3,C:80,PHP:90}]
  [....]
  [...]
  ]
  </code></pre>
  
  <p>Currently i am matching the studentId against students as </p>
  
  <pre><code>_.forEach(students,  function(student){
  _.forEach(student, function(st){
  if(st.id === studentId){
  //do something
  }
  });
  
  })
  </code></pre>
  
  <p>How can i achieve it with simple lodash commands. The goal is to avoid two forloops.</p>
  
  <p>Thanks in advance.</p>
