function WeakValueMap.clear(): void

Removes all entries from the map.

Example

type User = { id: string; name: string };

const user1: User = { id: "user-1", name: "Alice" };
const user2: User = { id: "user-2", name: "Bob" };

const cache = new WeakValueMap<string, User>();
cache.set("user-1", user1);
cache.set("user-2", user2);

console.log(cache.size); // 2
cache.clear();
console.log(cache.size); // 0
