Finally, flavors like std::regex and Tcl do not support lookbehind at all, even though they do support lookahead. JavaScript was like that for the longest time since its inception. But now lookbehind is part of the ECMAScript 2018 specification. As of this writing (late 2019), Google’s Chrome browser is the only popular JavaScript implementation that supports lookbehind. So if cross-browser compatibility matters, you can’t use lookbehind in JavaScript.
