JavaScript Maps, Sets, WeakMaps, and WeakSets Explained with Examples
we dive deep into the core concepts of JavaScript Collections like Map, Set, WeakMap, and WeakSet. You'll learn how to effectively use these data structures for storing and managing data. From basic operations such as set, get, delete, and has to more advanced concepts like WeakMap and WeakSet, we've got it covered. We also explore Object methods such as Object.keys(), Object.values(), and Object.entries() to further enhance your understanding of key-value pairs.
