Using single character variable names is always bad practice

Unless you are implementing some mathematical formula. Then link the paper and stick to its variables.

[–] jvisick@programming.dev 5 points 1 year ago

Mostly agree. I’m ok with single characters in a one line / single expression lambda, but that’s the only time I’m ok with it.

I have a convention to correlate the size of variable scope with its name length.

If a variable is used all over the program, it will be named "response". If it is <15 lines, then it can be "res". If it is less than 3 lines, it can be only "r".

This makes reading code a bit simpler, because it makes unimportant, local vars short and unnoticeable.

Why though? Intellisense helps you write out the full name. And instead of response why not call it whatever the data you're expecting to be

I agree because it makes the code easier to follow in 6 months time.

Sometimes you're just using it once and it's blindingly obvious what it is

[–] tryptaminev@feddit.de 3 points 1 year ago

To be fair everyone with poor documentation thinks the code is blindingly obvious when they write it.
