I am trying to fit ']' into my regex that lets any string pass as long as it doesn't have a certain set of special characters. However, the IDE shows me that it ends the expression:
message: Joi.string().regex(/^[^<>#*=+^}[]+$/).required()
//current working code
message: Joi.string().regex(/^[^<>#*=+^}[]]+$/).required()
//what I am trying to add
You can escape special character using \
So you can use:
(/^[^<>#*=+^}[\]]+$/)
which will escape the first ] allowing it to be viewed as a regular symbol.
If you are new to regular expressions, try regex101.com. It does a good job of breaking them down for you.
