I am a frontend dev. JavaScript (well, TypeScript) is my bread and butter. Even knowing its quirks I never would have thought how inconsistent Date actually is. I encourage everyone to try this quiz.

This is what JavaScript haters should bring forth, not 0.1 + 0.2 !== 0.3!

    There is a reason almost everyone use some Date lib, like Luxon and not the built in. And well, having a horrible built in lib that they can't change due to legacy code breaking is nothing really new or unique to JS.

    The built-in lib is fine for basic stuff unless you do some crazy shit like expecting "2" to parse as a valid date.

    For very basic things maybe, but it has a lot of other weird problems and restrictions. Mutability, no real timezone support, very limited arithmetic, to name a few. As soon as you move beyond the very basic, you want someting more robust.
