.number()
.int()
.default(1) // If value is `null` or `undefined`, then return default value `false`
married: racoon.boolean(),
favorite: racoon.object({ // You can define deep nested object format schema
sports: racoon.array(
racoon.string().min(1).max(100).required()

book: {
title: 12,
date: '2010-1-1'
}
}
});
} catch (error) {
console.error(error);
// Error: "favorite.book.title": value should be a type of string
// ↑↑↑ The error message can be customed
}
// If you don't like `try-catch` code style
// you can use `validateSilent` method
// If validate fail
// then `error` is not emtpy
// otherwise,`error` is `undefined`
// For Example:
const { error, value } = schema.validateSilent({ ... });
