Web Tools #443 - Frameworks, Testing Tools, Uncats (misc. tools)

Advertisement

I've always liked the suggestion to avoid using hard-coded values (often called "magic numbers") when writing code. Unfortunately, because all the work I do nowadays is on my own, it doesn't bother me to do something like this:

Without the comment indicating what this magic number is, anyone coming across the code wouldn't know why that particular value was used. The comment clears this up: It's the number of milliseconds in one hour.

As I said, for personal projects that others are unlikely to touch, I'm not against doing something like this. Even if I moved that value to a variable, I think a comment is enough info to help future maintenance of this code snippet.

But when working on larger applications in a team environment, or on projects that you may have to hand off to others, it's much better to do something like the following:

The above code sets the value in a constant that's clearly named so there's no confusion when it's used later in the code. Additionally, even when I define the constant, I'm not just hard-coding the value, but I'm "showing my work" via the comment and the full equation.

Now, you could argue that all this did was introduce three more hard-coded values. But I think in this case this is acceptable. These aren't values that are ever going to change and it's pretty clear what they do.

Of course, ideally you'd like to pull those numbers in from some kind of universal API that stores universal values or something. In that case, if all of humanity decides that they'd like to add more seconds to a minute or something like that, then the value would still be correct. But that's kind of nutty talk, so I think this solution is good enough! 😀

Now on to this week's tools!
