如何访问作为js Map中对象的键的值

Question

I am trying to store values in a JavaScript Map using an object as a key. However I am unable to access them using the get method provided by Map object. This is what I am trying to do -

let map1 = new Map();
map1.set({a: 1}, "valueforobject");
console.log(map1.get({a: 1})); //expected this to print valueforobject but got undefined

When I am logging the map itself however I can the that the value has been stored safely. How do I access this using the get method or any other way appropriate here?

This works. Take a look at the official documentation .

let map1 = new Map();
let keyobj = {a: 1};
map1.set(keyobj, "valueforobject");
console.log(map1.get(keyobj));
