What is the difference between `Array.prototype.reduceRight()` and `reduce()`?

Explanation

The key difference between `Array.prototype.reduceRight()` and `reduce()` is the direction of iteration. `reduceRight()` goes from the last element to the first (right-to-left), while `reduce()` goes from left-to-right. This impacts the result for non-commutative operations.

Key points

`reduceRight()` iterates right-to-left, `reduce()` left-to-right
Direction affects result for non-commutative operations
Both methods accumulate a value during iteration
