I want to throw an error message when user types in '&' in a textbox and the rest other characters and special characters are allowed.
Below code snippet throws the error message when '&' is the last character of the string like 'hello&', but I want an expression to find '&' anywhere in the string.
comments: yup.string()
.matches(/[^&]+$/, { message: 'error message', excludeEmptyString: true }),
