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-L981 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.
