title: Regex Javascript Phone number validation min max length check
body: <p>I want a very simple Regex for Javascript validation of phone number, which allows <code>10 digits</code> and checks <code>min numbers should be 10 and max 12</code> including <code>- dash two times</code> for ex. <code>123-123-1234</code></p>
  
  <p>I have found some on internet, but none of them is working for <code>min / max length</code>.</p>
  
  <p>Looking forward for quick response here.</p>
  
  <p>Thanks !</p>
