What are the best practices for using Set in JavaScript?

Using Set in JavaScript is great for storing unique values. Here are some best practices: 1. Use Set for unique collections. 2. Leverage methods like add(), delete(), and has() for efficient operations. 3. Convert arrays to Set to remove duplicates easily.

Can you explain how to convert an array to a Set?

Sure! You can convert an array to a Set by passing the array to the Set constructor. For example: const mySet = new Set(array); This will create a Set containing only the unique values from the array.

What are the performance benefits of using Set?

Sets provide O(1) time complexity for add, delete, and has operations, making them faster than arrays for these tasks, especially with large datasets.

Are there any limitations to using Set?

Yes, Sets only store unique values, so if you try to add a duplicate, it won't be added. Also, Sets do not maintain order like arrays do.
