## Example

```ts

import { number, object, optional, string, validate } from '@typeofweb/schema';

const personSchema = object({

  name: string(),

  age: number(),

  email: optional(string()),

})();

const mark = {

  name: 'Mark',

  age: 29,

};

const personValidator = validate(personSchema);

// If validation is successful returns data with correct type, throws ValidationError otherwise

const validatedPerson = personValidator(mark);

```
