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.

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

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.

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)
