How can I improve the performance of Ruby enumerables?

How can I improve the performance of Ruby enumerables?

You can improve performance by using methods like each_with_object, map, and select efficiently. Avoid using each when possible.

What about using inject? Is it efficient?

inject can be efficient for accumulating results, but be cautious with large datasets as it can lead to performance issues.

Are there any alternatives to map and select?

Yes, consider using filter_map for filtering and mapping in one pass, which can enhance performance.

How do I benchmark the performance of my code?

You can use the Benchmark module in Ruby to measure the execution time of your code snippets.
