title: Why 'datas' array is always empty?
body: <p>My code</p>
  
  <pre><code> $.getJSON('/load4',
      function (data) {
          for (var i = 0; i &lt; data.length; i++) {
              var counter = data[i];
              datas.push([counter.Id, counter.login.substr(0, 25),'3', counter.hash , 'MA']); 
          }
      });
  console.log("Datas " + datas);
  </code></pre>
  
  <p>I'm trying to fill my array like [[a,b],[a,c]], but can't.</p>
  
  <pre><code>datas[i] = [counter.Id, counter.login.substr(0, 25),'3', counter.hash , 'MA'];
  </code></pre>
  
  <p>Also doesn't work.</p>
