SyntaxError: invalid regular expression flag s in Firefox 70.0.1 (64-bit) #4

Closed dmnsgn closed 4 years ago

Error occurs in version 6.6.0. Works fine for 6.2.2.

Use Babel or another transpiling tool.

Firefox has not supported the s flag of es2018 for some reason. Node.js has supported it since 8.10.0.

@mysticatea Hitting the same issue and I am using Babel but since eslint4b is a dependency of my project it somehow isn't transformed.

To improve compatibility with browsers (4b :smile: ) could you try building / releasing the module including the @babel/plugin-transform-dotall-regex and see if it works in firefox then?

FYI version 6.5.1 works and since 6.6.0 it doesn't anymore in Firefox

I'm also hitting this issue, as our project is built with webpack we can't just use babel to post-process the bundle as easily.
