JS Regex on Curly Braces

Question

I have an example statement:

"function(){var x=0;if(true){var y=0;}}"

I have tried many expressions but they only return the "{var y=0;}"

I want to extract the following result:

["{var x=0;if(true){var y=0;}}","{var y=0;}"]

What is the best possible regex for this?

I only use JavaScript so lookbehinds are not possible.

@DavidThomas: You can do that for `{{{}}}` structure, but utterly fail with `{{}{}}` — nhahtdh, Jan 28 '13 at 00:23
@DavidThomas: Bracket balancing is not the only thing. Bracket can appear inside comment or string also. — nhahtdh, Jan 28 '13 at 00:29
Definitely have a look at a parser, e.g. http://esprima.org/. — Felix Kling, Jan 28 '13 at 00:33

I just tested the following with a JS Regex tester and it seems to work:

This Regex works only on 2 nested curly brackets, may not work with 3 or more but the Regex can be adjusted accordingly.

Kind regards,
