Explanation:
The array is: ['a', 'b', 'c']
.reduceRight() starts from the right (i.e., from 'c').
No initial value is provided, so:
First, acc = 'c', and it starts iterating from the second-last element.
Here's how it runs:
acc = 'c', val = 'b' → 'c' + 'b' → 'cb'
acc = 'cb', val = 'a' → 'cb' + 'a' → 'cba'
