TopicIsn't this the fastest way to do a for loop

#2:


readability is more important than typing slightly less. a rule of thumb is to never use ++, especially combining it with evaluation.

for (int x = 0; x < length; x += 1) {
}

one exception I allow myself is when you have a list of array accesses that all reference sequentially.

var x = -1;
Object.Property = values[++x];
Object.AnotherProperty = values[++x];
// etc...

it's less error prone not to actually type sequential integers. can also use a closure:

var x = -1;
Something next() => values[++x];

Object.Property = next();
Object.AnotherProperty = next();

(there's also a reason why I use ++x instead of x++ but can't remember.)

Doing it this way basically removes an opcode from every loop, right?
I don't think so, how could it? what opcode would be removed?

always going to be something like:

mov ax, 0
loop: cmp ax, length
jl done
<body>
inc ax
jmp loop
done:

might be able to eliminate a jump moving things around but I think that's the order things occur with a for loop.

The truth basks in scrutiny.
