Alright, listen up, y’all. We gonna talk about this thing called “refactories” or somethin’ like that. Sounds fancy, huh? But it ain’t nothin’ more than cleanin’ up your mess, just like sweepin’ the porch or washin’ the dishes. Only, this mess is made of code, you see. That gibberish them computer folks type all day long.
What’s the Big Deal with Refactories?
Well, lemme tell ya. Imagine you’re buildin’ a house. First, you just slap somethin’ together to keep the rain out, right? But then, as you live in it, you realize the door’s in the wrong place, the windows are too small, and the whole thing’s a jumble. Refactories is like rearrangin’ the furniture, knockin’ down a wall or two, and makin’ the whole house easier to live in. It don’t change what the house does, it just makes it better.
Now, with this code stuff, it’s the same thing. Programmers, they write code to make the computer do stuff. But sometimes, they write it in a hurry, or they’re learnin’, or maybe they just had too much coffee that day. And the code gets messy. It’s hard to read, hard to understand, and hard to change. That’s where refactories come in. It’s like takin’ that messy code and tidyin’ it up. Makin’ it so you can actually see what’s goin’ on, you know?
- Makes the code easier to read: Like writin’ big and clear instead of scribblin’ all over the place.
- Makes the code easier to change: If somethin’s broken, you can fix it without tearin’ the whole thing apart.
- Helps prevent bugs: Less mess, less chance of somethin’ goin’ wrong. Like keepin’ your kitchen clean so you don’t get ants.
When Should You Do This Refactory Thing?
Well, some folks say you should do it all the time, like washin’ your hands. Every time you see a little mess, you clean it up. Others say you should wait until things get really bad, like when the sink’s overflowin’. Me? I say, do it whenever it feels right. If you’re lookin’ at the code and you’re scratchin’ your head, thinkin’, “What in tarnation is this?”, then it’s probably time for some refactories.
Here’s a few more times you might wanna do it:
- Before you add somethin’ new: Clean up the space before you bring in more furniture, right?
- After you fix a bug: While you’re in there, might as well tidy up a bit.
- When the code smells bad: Yeah, code can smell bad. Not like rotten eggs or nothin’, but it just looks wrong, ya know? Like when somethin’ ain’t right with the food you are cooking, you just know.
How Do You Actually Do It?
Now, this is where it gets a little tricky. I ain’t no programmer, but I’ve heard ’em talk. They say there’s all sorts of fancy techniques, like “extract method” and “rename variable.” Sounds like a bunch of mumbo jumbo to me. But basically, it’s all about makin’ the code simpler and clearer.
Here’s some things them programmers do:
Keep it Short and Sweet
Don’t write long long lines of them codes that you yourself will get confused. It’s like talkin’. You don’t want to talk on and on without takin’ a break right? Just like when you are talkin’ to folks, you keep your sentences short so people understand you. Same goes for code. Don’t make it too long and complicated. Break it down into smaller pieces. And use lots of space, so it ain’t all crammed together like sardines in a can. Programmers call this “white space”, but I just call it “air”. Everythin’ needs air, even code.
Give Things Proper Names
You know how sometimes you call your dog “Spot” and sometimes you call him “Fido”? Well, that’s confusn’. In code, you gotta give things names that make sense and stick to ’em. If you call somethin’ “customer_name,” don’t go callin’ it “cust_name” later on. It’s like callin’ your eldest child by all of his siblings names or calling your husband by your last boyfriend’s name. It don’t work and everyone will be confused.
Don’t Repeat Yourself
If you gotta do the same thing over and over, that’s just plain lazy. Like washin’ the same plate over and over again. It’s nonsense. Same goes for code. If you’re sayin’ the same thing many times in the code, you find a way to say it just once. Programmers call this “DRY,” which stands for “Don’t Repeat Yourself.” Makes sense to me.
Keep It Simple, Stupid
This one I understand. Don’t try to be too clever. Just keep it plain and simple. The easier it is to understand, the easier it is to fix and change. No need to write code that even you don’t understand. That’s just plain stupid.
Use the Right Tools
Now, I’m not talkin’ about hammers and saws here. Programmers got their own tools, fancy programs that help ’em with this refactory stuff. They can find all the places where a variable is used, or automatically rename things, or even check if the code is still workin’ after they’ve changed it. That’s important, ’cause you don’t wanna break somethin’ while you’re tryin’ to fix it.
So, there you have it. Refactories ain’t nothin’ to be scared of. It’s just good housekeeping for code. Keeps things tidy, makes it easier to work with, and helps prevent problems down the road. And that’s somethin’ even an old woman like me can understand.
