How does lodash.isDate work?
lodash.isDate is a method provided by the Lodash library that checks whether the given value is a valid JavaScript Date object or not. It returns a boolean value true if the input is a Date object, false otherwise. The method checks the object's internal class using the Object.prototype.toString() method to determine whether it is a Date object.
