7 Mistakes Beginner Programmers Make • TechLila

By | April 8, 2022

Like any other language, programming is quite complex to learn, but that does not mean it is impossible to learn. In learning, one thing you should settle your mind on is that mistakes are inevitable. Matter of fact: if you are not making mistakes or encountering complexities, then you haven’t even started. But realizing that making mistakes is a part of the learning process will help keep you motivated when you feel like giving up and abandoning ship. 

If, for instance, you want to get started with Java programming language, you must have a good grasp of the peculiarity of Java, and that entails being aware of some of the Java errors beginners like you are guilty of and how to solve them. You can learn more about these errors in this post – replit.com.

The good news is that you can find out some of the mistakes most newbie programmers make and even learn how to avoid them before you get deep in programming. This article will take you through some mistakes that most beginner programmers make and how to avoid them. Please stick with us and learn something new.

1. Not Believing in Your Capabilities

As a beginner programmer, the worst error you can make is to doubt your programming ability. When you begin to believe that you are not capable of programming or that programming is too difficult for you, you have failed. Then you begin comparing your coding abilities to those of other programmers, most of whom have more experience than you do. And it is at this point that coding language takes on the appearance of an alien tongue that is nearly impossible to comprehend. Following that, you’re nearly prepared to abandon the code ship. Is this something you’ve previously heard? Here are some pointers on how to re-enter the fray.

  • Quiet your mind. Every success or failure begins in mind before becoming a reality. While you’re learning to program, resist the negative voices. Remind yourself that you are sufficient.
  • Enroll in online programming classes and practice exercises to boost your confidence. You can begin by exploring platforms such as CodeGym, Udemy, Udacity, or Coursera.
  • Practice while you learn. The key to success in coding is practice. Maintain a constant practice schedule while you are learning. Put everything into action, and if you must make errors, do not be afraid to do so. That is why the term “practice” is used.
  • Develop your coding skills by practicing with drag-and-drop programming languages. The goal here is to increase your confidence and assist you in easing into the programming space, not to foster dependency. To get started, you can use one of the following drag-and-drop programming language tools: Touch Develop, MIT App inventor, or scratch.
  • Associate with other inexperienced programmers and be willing to share your knowledge is critical.

2. Learning Many Languages At The Same Time

Another frequent error made by inexperienced programmers is the desire to learn multiple programming languages concurrently. They begin by learning Java and then move on to JavaScript without investing sufficient time in Java. They abandon Java in their excitement to learn the programming language and dive headfirst into the waters of Python, only to become befuddled. The concept of programming is most easily grasped when approached methodically. And that requires first mastering the fundamentals of one language before moving on to another.

When beginning your programming career, the following steps will help you avoid becoming confused:

  • Identify and master a language that fascinates you before moving on to another.
  • Establish your coding goals and focus your efforts on the tools that will assist you in accomplishing them.
  • If you’re unsure where to begin, consider using online coding resources such as CodeGym, Codeacademy, and others.

3. Coding with No End in Sight

Relying solely on inspiration and the thrill of programming to write code is one of the quickest ways to complicate your coding adventure. Naturally, there will be times when your mind is flooded with ideas, and you feel compelled to immediately begin writing code. As incredible as that code is, it is a surefire recipe for errors.

As a novice wishing to enhance their coding abilities, you must begin with the end in mind. This will aid you in comprehending the task at hand, weighing all possible outcomes, and effectively preparing for the complexity that has been identified. This requires a staged approach to coding.

Begin with the Thinking phase and work your way through to the Research stage. After acquiring significant data and knowledge, you proceed to the Planning phase before moving on to the Writing phase. After writing your code, validate it and make any necessary changes.

Maintaining a strategy while working enables you to code more effectively and avoid becoming confused along the way.

4. Attempting to Memorize Lines of Code or Algorithm

Another frequently made error is memorizing a line of code or an algorithm. As a beginning programmer, you should prioritize learning the details of how a particular syntax or class works and how to apply it over memorizing code and algorithms, which may be ineffective in a complex situation. Bear in mind that the beauty of coding is your ability to grasp the fundamental concepts, data structures, and design patterns, as well as their interaction to accomplish your goal.

If you’re having trouble recalling a particular class or syntax, you can refer to your notes, watch training videos, or even Google it.

5. Choosing to Ignore Debuggers

The vast majority of inexperienced programmers are unaware of the existence of debuggers or how to use them to evaluate their work. Debuggers are critical in programming because they assist you in troubleshooting issues by monitoring the behavior of each line of your program. As a beginning programmer, it is critical to understand what debuggers are, what they do in programming, and how to use them to step through the debugging process of your program. This will aid in your comprehension of the code’s operation.

If you can’t recall a specific class or syntax, you can refer to your notes, watch training videos, or even Google it.

6. Failure to Archive Your Work

If you’re new to coding, you may be familiar with the following sentence: “I’ve just lost hours/days of productive work due to my PC crashing.” What if your entire software ceased to function as a result of a single line of code modification? Does this sound familiar? Isn’t rewriting the program possible? However, this would entail wasting valuable time rectifying an error that could have been avoided if you had simply backed up your work online. Then there’s the question of how I can safeguard my job against unforeseen events.

Conduct research and select your preferred version control (VCS) system, such as Github, Gitlab, or Bitbucket, to store your primary work online while keeping track of your progress using Blogger.

7. Excessive Use of Comments in the Code

Comments are necessary for your code to prevent it from becoming alien to you over time and to describe the function of a particular piece of code. On the other hand, having an excessive number of comments in your code will make it difficult to understand.

Instead of attempting to explain the code, the solution is to use precise, simple, and informative comments. Additionally, keep your program’s visible comments to a minimum to keep things interesting.


Programming becomes easier once you are aware of the intricacies involved. However, being aware of how to avoid making similar errors in your programming journey is critical to programming success. Consider not understanding the value of debuggers or the importance of adding pertinent comments to your code. That will be vexing. However, now that you are aware, you can avoid these errors long before they become complicated.

Finally, if you’re considering signing up for a platform that exposes you to a variety of practical programming tasks, you can begin with CodeGym and learn to program by completing programming tasks.
