## Criteria

### Validation

These packages are capable of validating the data for type correctness.

E.g. if `string` was expected, but a `number` was provided, the validator should fail.

### Interface

It has a validator function or method that returns a valid type casted value or throws.

```ts
const data: any = {}

// `res` is now type casted to the right type
const res = isValid(data)
```

Or it has a type guard function that in a truthy block type casts the value.

```ts
const data: any = {}

function isMyDataValid(data: any) {
  // isValidGuard is the type guard function provided by the package
  if (isValidGuard(data)) {
    // data here is "guarded" and therefore inferred to be of the right type
    return data
  }

  throw new Error('Invalid!')
}

// `res` is now type casted to the right type
const res = isMyDataValid(data)
```
