What language is this? (from Beatport.com)

[joliett89]

Thats from the bottom of the main page with disabled CSS:

[% _.each(data.artists, function(artist){ %] Follow [%=artist.name=%] [% }); %] Follow [%=data.label.name=%]
[% if(data.saleType === 'purchase') { %] [% print(BP.functions.formatCurrency(data.price, "usd")); %] [% } else { %] View Track [% } %]
[% _.each(data, function(item){ %] [% var classes = [], active = '', small = ''; if(item.children){ classes.push('parent'); } if(item.played){ classes.push('played'); } if(item.parentId){ classes.push('child'); small = 'small'; } if(item.queuePosition === (BP.queuePosition||-1) ){ classes.push('active'); active = 'active'; } %]
[% if(item.type == 'track'){ %] [%=item.title=%] [% } else { %] [%=item.name=%] [% } %] [% if(item.artists){ %] [%=BP.functions.renderTemplate('tmpl-player-artists', item )=%] [% } %] [% if(item.label){ %] [%=item.label.name=%] [% } %] [% if(item.releaseDate){ %] [%=item.releaseDate=%] [% } %] [% if(item.type==="track"||item.type==="release"||item.type==="chart"){ %] [%=BP.functions.renderTemplate('tmpl-btn-buy-small', item)=%] [% } %] X
[% }); %]

It looks a little bit like JavaScript, but I am not sure...
By the way, how do you think the website is implemented (music store, about 250k hits per day)?
What programming language do they use (or what would be the best language for a site like that)?
Do they play (preview) tracks from the disk evrytime somebody wants to listen (reference to files in MySQL, but actual files read from a disk etc)?
Just wondering...

Thank you.

Drat. If you had been asking about a human language, I would not rest until I found the answer ;)

I keep slamming into references to the Umbraco CMS, with side excursions into ASP. At first sight I thought you were nuts saying it looks like JavaScript, but it really does, doesn't it? Just wrap all the Javascript braces {} in [% tags %] and you're there. Hmm. Makes it sound like the computer equivalent of pig Latin.

it looks like a templating syntax that didn't get processed on the server side.

Thats all from the main page, several sections combined.

[% data.size = data.size ? data.size : 'medium'; %] [%=BP.functions.formatCurrency(data.price, "usd") =%]
[% data.size = 'small'; %] [%= BP.functions.renderTemplate('tmpl-btn-buy', data)=%] 
[% switch(data.saleType){ case 'mixOnly': print(BP.functions.renderTemplate('tmpl-btn-mix-only',data)); break; case 'albumOnly': print(BP.functions.renderTemplate('tmpl-btn-album-only',data)); break; case 'download': print(BP.functions.renderTemplate('tmpl-btn-promo-dl',data)); break; case 'purchase': data.size = 'small'; print(BP.functions.renderTemplate('tmpl-btn-buy',data)); break; }%]
[% var rendered = []; _.each(data, function(genre){ genre.type = 'genre'; rendered.push( BP.templates['tmpl-item-link']({data:genre}) ); }); %] [%=rendered.join(', ')=%]

[%=data.title=%]

Do a search in Google for "BP.functions.renderTemplate". Something isn't quite right there. Google is indexing all that stuff. About 8,300,000 results.

People said it is a template for asp .net or encoded JavaScript (2 separate answers).

Thats from "View source":

<script type="text/javascript">var BP={};</script>

My guess is that BP might be an object (although I might be confusing it with an array; Beatport player on the top of the page) and JavaScript is encoded in some way?

I don't use it, but a Bing search suggests the above might be data-json
