An example of an AI chatbot conversation about best practices for JavaScript collections.
What are some best practices for using collections in JavaScript?
When working with collections in JavaScript, consider using arrays for ordered data and objects for key-value pairs.
Can you explain when to use Map instead of an Object?
Use Map when you need ordered keys, or when keys are not strings. Maps also have better performance for frequent additions and removals.
What about Set? When should I use it?
Use Set when you need to store unique values and want to prevent duplicates. It's great for membership checks.
Are there any performance considerations I should keep in mind?
Yes, prefer using Map and Set for large datasets as they offer better performance for certain operations compared to arrays and objects.
