What is the @ symbol in Javascript?

Question

I stumbled upon https://codereview.stackexchange.com/questions/10610/refactoring-javascript-into-pure-functions-to-make-code-more-readable-and-mainta and I don't understand the answer since the user uses an @ symbol in a way I've never seen before. What does it do when attached to the if keyword? Can you attach it to other keywords?

Answer 1

It's not a JavaScript thing. It's a symbol used by whatever templating system that answer was referring to. Note that the <script> element has type text/html, which will prevent browsers from paying any attention to its contents.

Some other JavaScript code will find that script and fetch its innerHTML in order to merge the template with some data to create ... well whatever that template makes.

Answer 2

@: syntax in Razor

It is razor code, not javascript, if you are interested in razor check: http://weblogs.asp.net/scottgu/archive/2010/07/02/introducing-razor.aspx
