In what world is

for (int index = 0; index < objectToIterate; index++)
{
    // DO YO THANG
}

less coherent than

for (int i; i < objectToIterate; i++)
{
    // DO YO THANG
}

The world where the convention is i

What's incoherent about the first one? Why is index bad beyond standards

[–] 9point6 1 points 1 year ago

It's not incoherent, it just takes a tiny bit more effort to mentally parse as it's not a stereotypical for loop. Maybe it's just me, but let me try and explain

With the i example if you're familiar enough with a language, your brain will gloss over the unimportant syntax, you go straight to the comparison and then whether it's incrementing or decrementing.

With the other example, the first my brain did was notice it's not following convention, which then pushes me to read the line carefully as there is probably a reason it doesn't.

I'm not saying it's a huge difference or anything, but following code conventions like this makes things like code reviews much easier cumulatively.
