title: How to access an element in 2d array in Smalltalk
body: <p>I started coding in Smalltalk and got stuck here. I have this 2d array:</p>
  
  <pre><code>testArr := Array new: 1.
  testArr at: 1
      put: ((Array new: 3)
              at: 1 put: '1A';
              at: 2 put: '1B';
              at: 3 put: '1C';
              yourself).
  </code></pre>
  
  <p>But if I want to access lets say first element of first array, what should I write to make it happen?</p>
  
  <p>Thanks!</p>
