The last year has seen a flurry of activity in JavaScript's standard library. New methods have been added to the Array and Set prototypes, and Objects and Maps are getting in on the party with new static functions. We'll take a look at what all these new methods do, how they fill the gaps in JavaScript that you have likely written functions for yourself, and how they prepare the language for future upgrades. With a better standard library, you can retire some dependencies and get excited about ES2024 and beyond.
