title: Remove spaces from a string, special characters and convert it to lowercase
body: <p>I need to format a string for comparison purpose.
  Lets say we have 
  <strong>Multiple Choice</strong>
  I want to convert it to
  <strong>multiplechoice</strong>
  So white spaces removed, any special characters removed and lowercase.</p>
  
  <p>I need to do this in SAPUI5 while comparing a value which I get from a model.</p>
  
  <pre><code>if (oCurrentQuestionModel.getProperty("/type") === "multiple choice")
  </code></pre>
  
  <p>How can I achieve this?</p>
