An example of an AI chatbot conversation about using maps in JavaScript.
How do I use maps in JavaScript?
You can use the Map object in JavaScript to store key-value pairs. Would you like to see an example?
Yes, please show me an example.
Here's a simple example:
let myMap = new Map();
myMap.set('key1', 'value1');
myMap.set('key2', 'value2');
console.log(myMap.get('key1')); // Output: value1
This creates a map and retrieves a value using a key.
What are the advantages of using maps over objects?
Maps maintain the insertion order of keys and can use any value as a key, unlike objects which only use strings.
