6 Common Coding Mistakes and How to Avoid Them

60% of STEM jobs are in computing. So it’s no wonder learning how to write code is one of the best skills out there.

But with so many common coding mistakes, new coders face a steep learning curve. You could find yourself glaring at your screen, straining to solve a problem. But by getting the basics right, you can avoid this fate.

So let’s take a look at 6 common coding mistakes. And how to dodge them. 

1. Messy Code: The Root of Most Common Coding Mistakes

Consistent code formatting helps you avoid hair-pulling problems. It’s easier to find things. You can trace errors faster. And anyone editing your code can make sense of it.

There’s nothing worse than facing walls of unindented, unformatted code. You need to prune it before you can work.

There are tonnes of resources for formatting. Even if you’re new, you will advance faster and with less stress. 

2. Lack of Proper Code Testing

There are lots of ways to tackle testing for codes. You can test your own. This helps you learn both sides of programming.

But bugs can sneak through the net. It’s like proofreading your own book, you miss things a third party would pick up. 

If a smooth function is crucial, it is best to hire a coder trained to test code.

3. Missing Comments in Code

Comments roadmap your code. You can label sections, explain why you did it that way, and mark sections for editing.

Stick to best practices for comments. This keeps things easy to read. And you will match what the pros are doing. A bonus is that by explaining your code, you enhance your learning process at the same time.

4. Learning Too Many Different Coding Languages

Many principles in coding stay the same across languages. You can get bogged down learning a dozen languages without learning coding basics. This gives you no advantages. And it wastes your time.

Stick to one versatile language first. Python and Javascript are common choices. 

If you know which area of coding you want to work in, choose the most relevant language. But the two above are ideal starting points.

5. Too Much Theory, Not Enough Practice

Lots of new coders dive into doorstopper textbooks. They learn all the formulas and algorithms. But when faced with a blank text editor, they get stumped. They missed practice.

You need to go through the frustration and elation of problem-solving. You need to make mistakes. You need to practice. 

Then all that theory will slot in like a well-oiled cog in your coding machine.

6. Where Are Your Backups?

“Data doesn’t really exist unless you have at least two copies of it.” – Jack Schofield, Computer Editor at The Guardian, 2008.

You’d be wise to learn Schofield’s three laws of computing. And the second, above, might be the most important. Why spend hours coding to lose it all in a power cut?

Back up to the cloud and a portable hard drive. But remember to encrypt sensitive files before uploading them.
