Goals
- Type checks with enumerated error codes
- String format type checks
- Array type checks
- Type guards (x is Type)
- Type assertions (assert x is Type and return; otherwise, throw)
- Customizable error messages (
ErrorMessageService.Map = /*Custom error code to error message format*/;) - Promise-based API available
Non-Goals
- Performance is not a goal; we are stressing safety, and usability over performance.
Promise-based API
While all type guards, and domain checks are synchronous, a promise-based API
may be desirable when wanting to validate a large number of conditions,
and using a final catch() to handle errors.
