isValid yup store in variable code example

Example: yup oneOf

// mixed.oneOf(arrayOfValues: Array<any>, message?: string | function): Schema Alias: equals
// Whitelist a set of values. Values added are automatically removed from any blacklist if they are in it. The ${values} interpolation can be used in the message argument.

// Note that undefined does not fail this validator, even when undefined is not included in arrayOfValues. If you don't want undefined to be a valid value, you can use mixed.required.

let schema = yup.mixed().oneOf(['jimmy', 42]);

await schema.isValid(42); // => true
await schema.isValid('jimmy'); // => true
await schema.isValid(new Date()); // => false
