isDate :: a → Boolean
import isDate from 'deep-waters/isDate';
const now = new Date();
isDate(now); // → true
isDate('01-02-2020'); // → false
import isString from 'deep-waters/isString';

const isEmail = compose(
isString,

);
isDate is built on top of ofClass validator and rely on
Object.prototype.toString
to check on the received value type in order to avoid typeof weird behaviours and encouraging a runtime strict type validation.Last modified 3yr ago
