The new Temporal API solves these issues with immutable-style methods that return new objects instead of mutating existing ones, explicit timezone handling, intuitive syntax for date arithmetic, and built-in formatting. Temporal is now in stage 3 of standardization and available in Chrome and Firefox for experimentation. ## Full article daily.dev links to this article rather than hosting it.
