The Post-MomentJS Era

According to their own documentation, new projects should no longer use MomentJS, mentioning its hefty size and its outdated architecture as the principal reasons behind this statement.

Although there are new libraries that they do recommend, we also have a different solution nowadays: no library.

Using ECMAScript Intl, we can go a very long way formatting dates without dependencies.

Intl.DateTimeFormat("en", {
    year: "numeric",
    month: "long",
    day: "numeric",
    hour: "numeric",
    minute: "numeric",
    hour12: false,
    timeZone: "CET"
}).format(new Date());
// -> September 15, 2020, 09:41

Intl.DateTimeFormat(navigator.language, {
    year: "numeric",
    month: "long",
    day: "numeric",
    hour: "numeric",
    minute: "numeric",
    hour12: false,
    timeZone: "CET"
}).format(new Date());
// -> 15 september 2020 09:41
// In dutch!

ISO formatting with Intl is tricky. But we don't need it.

new Date().toISOString();
// -> 2020-09-15T07:41:41.148Z

new Date().toISOString().split("T")[0];
// -> 2020-09-15

Have a look at the MDN docs for more information.

Even though Intl and Date are viable options, the MomentJS developers recommend a few libraries to help with some browser inconsistencies. Make sure to read the MomentJS post for all the pros and cons.
