How has Map and Set evolved in recent JS versions?

Map and Set were introduced in ECMAScript 2015 (ES6) and continue to evolve in subsequent JavaScript versions. They provide more efficient ways to manage collections of unique values or key-value pairs compared to traditional objects and arrays. In ES6, Maps can use any type of data as keys, while Sets store unique values. In later versions, improvements in performance and methods have facilitated easier manipulation and iteration over these collections, making them essential for modern JavaScript development.
