I know this is a simple question, but I am new to ASP MVC and just can't find the answer to this anywhere - what is the "@" that I am seeing everywhere? example:

```
@{
    ViewBag.Title = "Welcome";
}

<h2>Welcome</h2>

<ul> 
   @for (int i=0; i < ViewBag.NumTimes; i++) { 
      <li>@ViewBag.Message</li> 
   } 
</ul>

```
