Why is the naming convention for increment/decrement delta?
Why did we call delta as delta, and not "alpha" or simply "value"?
Delta can mean the difference between numeric values, which is aptly generic since that difference can be incremental or decremental. Another name could also just have been
difference and even a name like
value would be completely fine if you wanted something even more generic.
The naming of a value like this is very subjective so long as that name does not mislead potential readers of the code.
