Programming requires consistency and efficiency, but while programming beginners make some mistakes if not corrected can slow down the process or it would lead to bad coding practise. Recognising the mistakes and learning from it makes a confident and an efficient developer

In this blog article we will dive into 7 common mistakes that beginners often make and how to fix them.

  1. Jumping into Code Without Understanding the Problem

  2. Many beginners makes the mistake of doing code without knowing the problem, this leads to wastage of time, and feeling frustrated

    How to Fix It:

    • Read the problem statement thoroughly

    • Writing the flowchart or pseudo code

    • Break the problem statement into smaller parts

    • Identifying the input, output, constraints

  3. Not Using Meaningful variable and Function Names

  4. Variables and function names should be meaningful as when after few years we look out the old codes we should be able to understand the codes. Using too long variable names also tends to mismatch

    How to Fix It:

    • Use descriptive names like totalAmount, isLoggedIn or calculatePrice()

    • Making function names action oriented like getUserData(), getUserEmail()

    • Following a consistent naming style like camelCase or snake_case

    • Avoid abbreviations

  5. Ignoring Code Comments

  6. When coding many beginners don't write comments as without comments makes it harder for knwoing the purpose of code

    If a short comment is added it will help to identify the purpose of the code later

    How to Fix It:

    • Writing a short comment on above the code makes it helpful for identifing the purpose of code

    • Use Inline comments for any complex logic

    • Using a consistent comment style like ( // for single line in most languages).

    • In a team project commenting is crucial and it should be clear and to the point.

  7. Breaking the DRY Principle (Don't Repeat Yourself)

  8. Many beginners tend to use the same code everywhere instead of using loops or function. For example, to display cards for a service section from the database, instead of repeating code, use a loop to reduce redundancy and follow the DRY principle.

    How to Fix It:

    • Writing a short comment on above the code makes it helpful for identifing the purpose of code

    • Use Inline comments for any complex logic

    • Using a consistent comment style like ( // for single line in most languages).

    • In a team project commenting is crucial and it should be clear and to the point.

  9. Copy Pasting Code Without Understanding It

  10. Beginner often start writing code by copy pasting which leads to not understanding the code and reduce the confidence of building any project from scratch.

    How to Fix It:

    • Always try to write the code after learning the concept

    • If you are copying the code then try to understand each line and the reason of using it and if there's a better approach of doing then try to implement it.

    • Experimenting the copied code and observe the result

    • Use refrences but try to code in your own

  11. Not Practicing Enough

  12. Programming requires consistency if not done regularly you will feel less confident and make more mistakes.

    How to Fix It:

    • Practice coding daily even for 30 minutes

    • Make it a priority and avoid procrastination

    • Try to build the project from scratch and practice coding problems.

    • Fix the schedule and allot a specific time for code

  13. Ignoring Code Readability and Formatting

  14. Beginner often write code without proper formatting it leads to messy and makes it difficult to debug and understand.

    How to Fix It:

    • Follow Indentation and spacing.

    • Break down the long lines of code

    • Use consistent bracket placement

    • Group related lines together with blank lines in between.

Conclusion

We should remember making mistake is part of becoming a great programmer. We should not avoid the mistakes but to recognize them and learn from it. By avoiding the above 7 common mistakes you will make a strong foundation for writing clean, efficient code and remember that every great programmer was once a beginner who overcomes the mistakes and kept on improving
