Description

Type casting converts values from one type to another. The cast() method transforms the input value into the target
type, throwing InvalidArgumentException if conversion is impossible. Unlike assertions which validate existing types,
casting actively transforms values (e.g., string "123" becomes integer 123, or "yes" becomes boolean true).

Casting is ideal for normalizing data from external sources like CSV files, API responses, or user input.

Cast list elements between types. Convert arrays of strings to integers or vice versa with automatic element casting.
