Ever wear a suit to an interview? Same thing.
Nobdy's going to pay a front end developer $95K/year if they think he's coding stuff like this all day long:
form1.user_name.value = 'John Doe';
form1.user_name.onclick = function() { form1.user_name.value = ''; }
But if you start flapping your gums about MVC, node, Angular, backbone, AJAX, RESTful, or JSON...they think you're at the forefront of Computer Science.
It's the same with PHP frameworks. Any CRUD app coder earning $40K/year can write this all day long:
$user_name = trim(strtolower($user_name));
echo 'Your name: ' . $user_name . '
';
But if you start mentioning MVC, Yii, Laravel, Symfony, or Zend...it's like putting on a tweed jacket with patches on the elbows and holding a coffee cup that says "Professor of the Year".
