An example of an AI chatbot conversation about data structure choices in JavaScript.
What are the best data structure choices in JavaScript?
In JavaScript, common data structures include Arrays, Objects, Sets, and Maps. Each has its own use cases.
Can you explain when to use an Array versus an Object?
Use Arrays for ordered collections and when you need to access elements by index. Use Objects for key-value pairs.
What about Sets and Maps? When should I use those?
Sets are great for unique values and fast lookups, while Maps are ideal for key-value pairs with any type of key.
Are there performance considerations I should be aware of?
Yes, performance can vary. Arrays are fast for indexed access, but Objects can be faster for key lookups. Always consider your specific use case.
