What are the differences between arrays and sets in JavaScript?
An example of an AI chatbot conversation about the differences between arrays and sets in JavaScript.
What are the main differences between arrays and sets in JavaScript?
Arrays are ordered collections that can contain duplicate values, while sets are unordered and only allow unique values.
Can you give me an example of when to use a set instead of an array?
Sure! Use a set when you need to store unique items, like a list of user IDs, to avoid duplicates.
How do I convert an array to a set in JavaScript?
You can convert an array to a set using the Set constructor: const mySet = new Set(myArray);.
Are there any performance differences between using arrays and sets?
Yes, sets generally have faster lookups for existence checks due to their unique value constraint, while arrays can be slower.
