python to javascript regex

Question

Can someone help me to fix this regex to use in javascript?

(?<!\\\\)#\\{{1,2}

Regex tester said:

SyntaxError: Invalid regular expression: /(?:((?<!\\)#\{{1,2})|(.))/: Invalid group

Thanks.

can you help me remake it? i don't have any experience with regex :( it was for slim-template hightlighting in texmate. '#embedded-ruby': [ { token: 'punctuation.section.embedded.ruby', regex: '(?<!\\\\)#\\{{1,2}' — Terry Sahaidak

maybe /(?:((?!\\)#\{{1,2})|(.))/. in python negative lookback is (?<!...) but in javascript is (?!...) just remove <
