title: How to enable syntax errors/warnings highlighting in atom
body: <p>So I was using Aptana Studio before, and now I switched to Atom.</p>
  
  <p>And I got used to Aptana's errors and warnings highlighting.
  For example if I forgot <code>;</code> after declaration of a varible, or wrong brackets and etc...</p>
  
  <p>In Atom I don't see any errors/warnings highlighting at all. Is it even possible to enable it in stock Atom, or should I download any additional packages? </p>
  
  <p>P.S. I'm working with JS/JQuery/Node/PHP/HTML</p>
