title: Javascript + HTML - Difference between ' ' and " "
body: <p>This is a question for my personal knowledge.</p>
  
  <p>Why does <code>Javascript</code> use <code>" "</code> for Strings (<code>var myString = "test"</code>), but for example when I try to call a function that has a string as a parameter I have to use <code>' '</code> ?</p>
  
  <p>What is the difference between them ?</p>
