JavaScript regex with escaped slashes does not replace

Question

Do i have to escape slashes when putting them into regular expression?

myString = \'/courses/test/user\';
myString.replace(/\\/courses\\/([^\\/]*)\\/.*/, \"$         


        

Answer 1

Actually, you don't need to escape the slash when inside a character class as in one part of your example (i.e., [^\/]* is fine as just [^/]*). If it is outside of a character class (like with the rest of your example such as \/courses), then you do need to escape slashes.
