What is the regular expression to split on comma (, and newlines) except if comma is escaped? For example:

foo,bar,baz = ["foo", "bar", "baz"]

BUT

foo,bar\,baz,42 = ["foo", "bar,baz", "42"]

Looking to use in javascript#: value.split(/[\r\n,]+/g);

Thanks.

`/(?<!\\),/g` should do it. – Aniket Sahrawat Mar 20 '18 at 13:43
Just do a match on `/(?:(?:\\{2})*\\,|[^,])+/g` instead of splitting. – ctwheels Mar 20 '18 at 13:44
