title: Difference between jquery-rails & jquery-ujs
body: <p>I have googled around a bit, but haven't been able to figure out what the exact difference between the two is. From the jquery-rails read me (<a href="https://github.com/indirect/jquery-rails" rel="noreferrer">https://github.com/indirect/jquery-rails</a>) it seems that jquery-ujs complements it, but I'm not sure why/how.</p>
  
  <p>Would appreciate it if someone could break this down to me.</p>
  
  <p>Thanks.</p>
