4 Reasons Why You Shouldn’t Mess with Code If You Don’t Know What You are Doing

4 Reasons Why You Shouldn’t Mess with Code If You Don’t Know What You are Doing

As a programmer, you understand how frustrating it is to operate on someone else’s code. If you don’t know what you’ve been doing, don’t mess with code.

if you ever mess with code then call for help

If you’ve been a programmer for more than two or three years, you’ve most likely been substantially negatively affected by someone else’s defective code. The slowdown can be severe, and you can find yourself going at a crawl. Any adjustment you introduce to the code can cause other parts of the code to break. Any addition or alteration to the system must be understood before more adjustments can be made. Over the years, the mess can become so large and deep that it is impossible to clean. There isn’t anyway.

As the mess grows, productivity plummets almost to zero. As productivity declines, more personnel will be added to the project with the expectation of higher efficiency. However, since they are unfamiliar with the system’s architecture, they, too, are unable to change it. Furthermore, under tremendous pressure to maximize productivity, they begin to make more and more messes, driving productivity ever closer to zero.

Don’t Mess With Code

It is preferable to go over the code before continuing. Often it’s just not worth altering, but if it’s tiny enough, you can do a one-time rewrite. However, do not modify the central or vital code that others depend on or regularly use without first obtaining approval or conducting a code review. As a result, it is often advantageous to write code from the ground up for better performance.

Making errors is part of being human. Many of the mistakes that developers make, however, can be minimized. If you can avoid the common errors discussed in this article, you will be able to compose better and cleaner code. This will be helpful not only to you but to the other developers who will be reviewing your code. So you’re not just doing this for yourself; you’re also doing a big favour for your team. Here are some of the most fundamental mistakes to avoid.

  • Commented-Out Code

Commented out Code

We’ve all seen whole blocks of code with several functions commented out. Nobody knows why it’s still standing. Nobody knows if the commented-out code is still applicable. However, no one deletes the block of code, which is precisely what you can do with it. Everyone believes that this block of code would be used by someone else, which is why no one deletes it.

Remove the commented-out code. And if the code is not in the most recent revision, it is still accessible in the source code if anyone has plans for it.

  • Magic Numbers

Magic numbers are one-of-a-kind values with no explanation or multiple occurrences that can and should be effectively replaced by named constants. Magic numbers are frequently used several times in various locations within a program, posing a significant threat to errors.

  • Messy Formatting of Code

People who don’t have a lot of programming experience are prone to mess with code configuration. If you specifically ask most developers with several years of professional experience to recognize a tester or data scientist who mess with code formatting, they would probably shake their head. This is due to a lack of knowledge—unless they’re using a programming language like Python, which eliminates this.

Using a linter is among the most popular methods for dealing with weak formatting. Both modern IDEs have the ability to fix this for you as well. Often you need to install a plugin, and other times you can do it right away.

  • Hard-Coding

Hard Coding

Hard-coding is the process of embedding data directly into the source code of a program or other operational objects instead of extracting the data from external sources or creating it at run-time in software development. Hard-coded values do not permit configuration; they are fixed in concrete. Hard-coding is regarded as an anti-pattern or, at the very minimum, a very poor code smell.

Passwords and file locations are the most commonly hard-coded items for whatever (sometimes even justified) purpose. If you find yourself hard-coding a lot of stuff, you should take a close look at your code because it isn’t always the right solution to problems.

Final thoughts

To reach the deadline, most developers are forced to produce mistakes. It’s how a lot of mess with code is created in the first place. However, as soon as you make a mistake, you’ve already decelerated. When you make mistakes, you can’t go quick in the long term, and being effective in the long run makes a project successful.

Professional coders who have honed their skills understand that making a mistake is never faster. In certain instances, the chaos you just created to reach the deadline would cause you to miss it. The only way to meet your current and future deadlines is to keep the code clean.
