title: "jQuery(...)" instead of "$(...)"
body: <p>Is it a good practice to write <code>jQuery("...")</code> instead of <code>$("...")</code>?</p>
  
  <p>I heard that it might be useful for avoiding future conflicts with other libraries if they use the <code>$</code> as well, but is that a real-world concern? Let say I really have no idea what other libraries I'm gonna use in the future, so should I avoid writing <code>$("...")</code> in my scripts? Is there any other well known libraries relying on <code>$</code> as well?</p>
  
  <p>Also I'd love to know if there is any other issues attached to this subject.</p>
