After first look through documentation, I don't understood, how:

1. How do I check for example are password and confirm password fields in object equals?
2. How can I set custom error message for internationalization purpose?

Sorry for dummy questions

Hey, no worries! For 1, I'd do something like this:

const form = type({
	password: "string",
	confirmPassword: "string"
}).narrow((data, ctx) => {
	if (data.password === data.confirmPassword) {
		return true
	}
	return ctx.reject({
		description: "identical to password",
		path: ["confirmPassword"]
	})
})

2 is a bit more complex. There are customizations available for error messages but they do need more documentation and particularly around internationalization I'm trying to figure out the approach that will integrate best with popular i18n libraries. May be worth checking out the Discord and some of the conversations there around this:

Would love to get your feedback! For now you can certainly map over ArkErrors and inspect the code and map the message based on the core error info.
