Getting a value associated to the key
suggest changeTo get a value associated to the key, use the .get()
method. If there’s no value associated to the key, it returns undefined
.
const obj1 = {},
obj2 = {};
const weakmap = new WeakMap([[obj1, 7]]);
console.log(weakmap.get(obj1)); // 7
console.log(weakmap.get(obj2)); // undefined
Found a mistake? Have a question or improvement idea?
Let me know.
