title: How to convert a whole list of string to integer values in Scala
body: <p>So, I have a list of strings like this.</p>
  
  <pre><code>val x = List("12", "33", "77")
  </code></pre>
  
  <p>Is there a way to convert this whole List into integer values, like the following, without using a for loop?</p>
  
  <pre><code>result == List(12, 33, 77)
  </code></pre>
