JSLint “insecure ^” in regular expression

Question

JSLint reports Insecure \'^\' for the following line. Why is that? Or is it just going to complain any time I want to negate a character class?

// r         


        

Answer 1

Consider using \W instead of /^\w/

"!$7s-gd,&j5d-a#".replace(/\W/g, '');

For your particular case this would not work because you want to leave comma and dash characters, but I think it is worth mentioning.
