This should be a Show HN.
I read the code, and I do not think this library is suitable for real-world use.
Consider `makeTestType` (https://github.com/imbrn/v8n/blob/master/src/v8n.js#L973-L98...):
return () => value => {
return (
typeof value === type ||
(value === null && type === "null") ||
(Array.isArray(value) && type === "array")
);
};
This means that null and "null" (as a string) are now numbers.
v8n().number().test("null") // true
It also means that an array of numbers is a number... something that is counterintuitive for the user of the library.
In addition to that, most of the time you want to deal with finite numbers. A validation library should have an API that reflects this, but this is not the case for v8n.
