I know I can combine Validator.js with Zod to check if an input is alphanumeric. However, is there a built-in way with Zod to check for alphanumeric WITHOUT having to use regex?
Zod does not have those, because their regex implementation is straightforward (unlike email or IP(it checks for numbers to be 0-255)), and if implementation for your case is not it recommends using validator.JS (e.g. language-dependent alphanumeric)
