Can I use colons as variable names in Javascript?

Question

Is there a way I can use variables with colons in them as variable name? I would need this for facebook where I have to pass it on as parameters:

FB.api('me/namespace:action', 'POST',
{
  og:type : type,
  og:title : title,
  fb:explicitly_shared : true
});

for example. How would I do this here? When I tried it didn't quite work out..

Answer 1

Try this:

FB.api('me/namespace:action', 'POST',
{
  "og:type" : type,
  "og:title" : title,
  "fb:explicitly_shared" : true
});

Note that these aren't "variables", they're object property names. Property names can be just about any valid JS string if you put them in quotes.
