Is this value a JS Date object? This module works cross-realm/iframe, and despite ES6 @@toStringTag.
The is-date-object npm package is primarily used for checking if a given value is a Date object. It is a simple utility that can be very useful in situations where type checking is necessary, especially when working with dates in JavaScript. This package provides a straightforward and reliable way to determine if a value is an instance of a Date object.
Check if a value is a Date object
This feature allows you to check if a given value is a Date object. The function returns true if the value is a Date object, and false otherwise. This is particularly useful for validation and error handling in applications that deal with date inputs.
const isDateObject = require('is-date-object');
console.log(isDateObject(new Date())); // true
console.log(isDateObject('2020-01-01')); // falsedate-fns is a comprehensive date utility library that offers a wide range of functions for parsing, validating, manipulating, and formatting dates. Unlike is-date-object, which focuses solely on checking if a value is a Date object, date-fns provides a broader set of functionalities for working with dates in JavaScript.
moment is another popular date manipulation library that offers functionalities similar to date-fns, including parsing, validation, manipulation, and formatting of dates. While moment is more feature-rich compared to is-date-object, it is also larger in size, which might be a consideration for projects concerned with bundle size.
dayjs is a lightweight date library that offers a similar API to moment. It provides a wide range of functionalities for working with dates, including parsing, validation, manipulation, and formatting. Dayjs is a good alternative to is-date-object for projects that require more comprehensive date handling capabilities but still want to keep their bundle size small.
