This package provides reliable and performant checks for various data types, extending beyond JavaScript's built-in typeof operator. It includes checks for numbers, strings, objects, arrays, functions, and more, often with specific, useful conditions like checking if a number is positive or a string is an email. check-more-types helps improve code clarity and robustness by providing explicit and descriptive type validations.
