SyntaxError: Invalid regular expression: missing / [closed]

Question

According to http://www.regexr.com/38o5d my reqex seems to work, but when I implement it into my javascript

var prefix = hash.replace(/\/|#/g, '');

I'll get the following error: SyntaxError: Invalid regular expression: missing /

Answer 1

Psychic debugging: Your code isn't in a plain JavaScript or HTML file, but is being printed from a scripting language in which # is a comment character. The #/g, ''); piece is being treated as a comment in your script.

You need to add some quotes to ensure that the whole line gets printed.
