How does validator.isDate work?

validator.isDate is a function that determines whether a given value is a valid date by checking if it is a valid date string that can be parsed by the JavaScript Date object or if it is a valid Date instance. The function also allows for the validation of custom date formats by accepting a second parameter specifying the format.

const validator = require("validator");

const dateString = "2023-04-03";
const isValid = validator.isDate(dateString);

console.log(isValid); // true

In this example, the validator module is first imported. A date string dateString is then defined as '2023-04-03'. The validator.isDate method is used to check if the string is a valid date. The result is then logged to the console, which will print true.
