How can I use a map with nested objects in JavaScript?
You can use the Map
object to store key-value pairs, where the values can be nested objects. For example, you can create a map like this: const myMap = new Map(); myMap.set('key1', { nestedKey: 'value1' });
.
How do I access a nested value in that map?
To access a nested value, you can first get the object from the map using its key, then access the nested property. For example: const value = myMap.get('key1').nestedKey;
.
Can I update a nested value?
Yes, you can update a nested value by first retrieving the object, modifying the property, and then setting it back. For example: let obj = myMap.get('key1'); obj.nestedKey = 'newValue'; myMap.set('key1', obj);
.
What if I want to iterate over all entries in the map?
You can use the forEach
method to iterate over the map entries. For example: myMap.forEach((value, key) => { console.log(key, value); });
