Ok, I get that the Date API is problematic, but I wouldn’t expect anything meaningfull from new Date("not a date").getTime() anyway. Why would you in the first place?

Luckily the new Temporal API is shaping up.

Until the new Temporal API comes along, there are some libraries we can use.

• luxon
• dayjs
• or compile chrono (Rust) to WebAssembly

In the process of being replaced.

JavaScript has had the Date object for handling date and time since its first days. However, the Date API is based on the poorly designed java.util.Date class from Java, which was replaced in the early 2010s; but, because of JavaScript’s goal of backward compatibility, Date sticks around in the language.
