I think it is better to stop using this "~~ in 2018" style of writing. It is not like everything in CS gets obsolete every year. For example, Berkeley sockets are still used today as well as many other libraries. So you don't have to switch to some other libraries only because it was written several years ago and you don't have to use arrow functions instead of `function` keyword only because it is 2018.

Nobody is implying anything before 2018 is obsolete, but that these libraries that the author is showing are still alive and well and actively maintained/improved. Sure, a js library from 2008 will still work great now, however it might not work well with new module bundlers, or it might do something that is consitered "code smell" in newer JS engines which could impact performance. Newer doesn't mean "better", but it's still useful information to have.
