Summary

C# 8 introduces new features to improve array access, including index from end operators and ranges. The index from end operator allows developers to access elements from the end of an array using a ^ symbol, similar to negative indexes used in other languages. Ranges provide a concise way to slice out chunks of an array, allowing developers to easily perform common operations like averaging random samples from a dataset. While some objects in C# support these new features, others do not, and developers should be aware of the limitations and gotchas associated with using them. Overall, these new features can make development easier and more efficient, especially for tasks that involve array access and manipulation.
