[removed] negative lookbehind equivalent?

Question

Is there a way to achieve the equivalent of a negative lookbehind in javascript regular expressions? I need to match a string that does not start with a specific set of cha

Answer 1

This effectively does it

"jim".match(/[^a-g]m/)
> ["im"]
"jam".match(/[^a-g]m/)
> null

Search and replace example

"jim jam".replace(/([^a-g])m/g, "$1M")
> "jiM jam"

Note that the negative look-behind string must be 1 character long for this to work.
