log(ele)) //Uncaught TypeError: map.map is not a function 2.2 Map 缺点和 WeakMap 优点 1.赋值和搜索操作都是 O(n) 的时间复杂度,因为这两个操作都需要遍历全部整个数组来进行匹配。 2.可能会导致内存泄漏,因为数组会一直引用着每个键和值。 相比之下, WeakMap 持有的是每个键对象的 “弱引用”,这...

It models the mathematical function abstraction. The Map interface includes methods for basic operations (such as put, get, remove, containsKey, containsValue, size, and empty), bulk operations (such as putAll and clear), and collection views (such as keySet, entrySet, and values). ...
This class provides all of the optionalMapandSequencedMapoperations, and it permits null elements. LikeHashMap, it provides constant-time performance for the basic operations (add,containsandremove), assuming the hash function disperses elements properly among the buckets. Performance is likely to be...
