Sometimes there is no alternative to Moment.js

[Wernfried]

Moment.js can be still a useful (and perhaps even the only) library.

JavaScript is a widely used language, not only used by web-browsers.
Most alternative libraries require access to the internet in order to connect to the IANA timezone database and/or rely on Intl Object.

When you use for example mongo shell then

• you don't have connection to the internet
• the shell does not support Intl object. The new mongosh is still in beta-phase
• you don't care about a 300k library. With MongoDB scripts you process much larger documents. Other popular libraries like Node.js or mongoose are even larger.

I am really happy that moment.js is still maintained. So far I did not find any suitable alternative library.

According to their own docs, the maintenance is minimal: https://momentjs.com/docs/ (I would have called it life-support)
