We all know what bad code looks like. But it’s much harder to tell how to avoid this outcome and what to do to make your code robust. Below you will find some insights into how to write better code: tips & tricks from GRT developers that, if applied, will help you to produce the truly high-quality software.
Okay, you might be wondering: what does this have to do with anything? Although this will not make you a good coder right away, if you actually spend time reading other people’s great code and getting better with algorithms and data structures, quality in your own code will follow. Just trust us on this one
When was the last time you took the time to actually write how you will go about a particular project? It’s easy to start the project thinking that you know exactly how it is going to be structured, but eventually you will probably realize that you need to go back and rewrite at least some part of your code. To avoid this, it is very important to plan your project from start to finish.
There is nothing more useful than commenting your code. Just think about it: if you write a procedure, fail to comment it, and then return to it in a few weeks (and you will), not having comments will cost you time, which is your most valuable resource.
Without source control, it’s really hard to make programmers work together efficiently – there is no way to know what other people did. With source control you will be able to revert mistakes easily. And it also checks out the code on every programmer’s hard drive, which prevents the loss of code.
You have probably never taken a hard look at the open source code you use before. If you do, you will probably find a few bugs that need to be fixed. If you actually commit to fixing them, you will need to identify and fix bugs in multiple languages, you will need to work with others to integrate your fixes, and you will learn a couple of new systems. This will take your skills and experience to the whole new level.
Even the best developers make errors. Ask yourself, “If a crazy person passed this all sorts of backwards values, how can this poor piece of code protect itself and keep the device from exploding?” Then write your code to check for and defend itself from this weird data. For instance, if you are passing arrays or pointers, then you’d better be watching for errors or bad data. Good error checking makes the program faster to debug and saves you tons of time overall.
Be familiar with and follow best coding practices to write better code.
This one does not even require explaining. Learning the best practices of the software development process is an extremely important component to writing better code.
And here is a joke for you in the end of this article (and something to think about):
The only valid measure of code is WTFs per minute.
