15 Critical mistakes every programmer must avoid

Without a doubt, programmers or developers work well with many platforms to come up with an ideal software solution. However, it is important to keep in mind how things are working according to requirements, coding and testing.

However, there are some mistakes that need to be considered or ignored at any cost to become a good programmer. So, here is a list of some mistakes that programmers should ignore in order to thrive in the world of coding.

Fast and loose

Try not to tumble off the shore or miss out a step while running in the race of software development. Working on code requires time and concentration. Therefore, it is important not to rush into it as it can confuse the programmer. Be sure to include work on the code in a way that does not affect user behavior. A stupid mistake can cause your software application to run late.

Theoretical knowledge

Developers focus primarily on theory rather than practicing critical code. Theory can help memorize details or keywords or learn key details of program platforms but unless a developer can work and practice them, it is of no use. It’s important to focus on the big picture, understand the code, and apply it.

Spending time on the research of technologies

It’s great for developers to learn about a new technology or other platforms. But if you don’t have a perfection on the platform you’re focusing on the rest of the bus will go down the drain for developers. Developers need to complete a platform before diving into another language or framework that can go a long way in the training phase of programming.

Obsession with tools

We live in an age full of options for technologies and tools that make it easier for developers to work on codes. Anyone can easily learn the code and work around the platform but being obsessed with tools and technology is not the ideal approach to go for a programming platform.

Genius, No Genius

Programmers feel it is important to be able to crack a code or solve a query. The fact is that there is a lot of talent and skills that are important when it comes to development. It is common for developers to leave when a new question arises. But trying is a matter of coding that makes a whole new difference in the world of development.


Print data values ​​and variables are simple and fast for developing preview results. The print that fits in the code allows to control the flow of data through a piece of code and quickly identify errors.


Explain what a piece of code is made of using comments is a simple and effective form. Comments can be very helpful in understanding a piece of code and how it relates to the rest of the program.

A lot of people make “think ugly” comments in the code, but this is almost a standard practice in software engineering. Comments are quick to help you “remember” after a long time without remembering the work of a particular part of the program.


The debugger code represents the logical consequences of a part of the program. So programmers can go one by one and check everything as variable values. Debuggers are available with a variety of features in most languages, including some graphical interfaces and break point settings in the execution environment.

Bug tracker

This is the annotation system for bug tracking, important for any software project. By creating this “bug file”, you can sometimes avoid losing information that is important for resolving problems during program development. Without Bug Tracker, it is very difficult to identify and identify bugs because we rely on memorabilia or scattered notes created by ourselves or a programmer.


Some languages   perform static analysis on the code so that it can be very useful to check the content before compiling or executing errors. Use a linter before compiling or executing the code, it helps to detect and correct bugs in the software before it is executed. This exercise saves time in detecting syntax and typing errors.

Version control

After tracking, find and fix bugs in a program so you can gain control over the codes that are being used and that have been modified. It is possible that some positive changes in the modality of that program may have negative effects on each other.

So creating a version control in software engineering for any project is the best practice and should not be ignored.

There are many systems for controlling versions that are available for free on the Internet for use in your projects. Such as Git, Mercury and SVN which allow us to organize, document and track different versions of the code. Different versions of the code can be shared by multiple programmers, for example, and they can work simultaneously without creating errors that affect each other’s progress.


Improperly placed in the software can be a headache for fixing important code bugs. When the code is easy to understand, it is easy to run and errors can be detected quickly.

The best way to ensure code is easy to understand is to write applications that do just that. Create mods for functions and processes that are important to your software, so you can isolate specific points of the program and bug fixes can be done quickly and efficiently.

Create software components that do only one thing called code modulation. This type of program helps to understand software systems more easily. Modularization creates a level of abstraction that simplifies the understanding of a particular program block without understanding the system in full detail.

Automatic test

Unit testing and other types of automated tests can easily be done using modernization. You can run a piece of code with entries and specific data to see what is expected of the program’s outcome.

It is much easier and faster to test the functionality of a task or class method than to test applications that confirm the general behavior of a program. There are many tools available to help you run tests on your programs.


Legend has it that Brian Karnighan and Rob Pike, who started in a computer college – a teddy bear, also known as a rubber duck.

Students should sit in front of a teddy bear and tell him about his mistakes before looking for a teacher or someone “alive”. Believe it or not, this refining technique is very effective and has spread all over the world of software engineering and is still used today.

The important part about this method is to explain the code and the problem loud, clear and concise. The speaker’s cause is the “outside” view of the problem itself and in most cases the solution is found on its own.

Some programmers turn a teddy bear into a “rubber duck.” A common and useful technique is to keep a daily schedule where the effects of the code are recorded before and after implementation.

Create program documents

Software documents describe system features that are available to users. Write documentation of greater understanding and understanding of the system as a whole. And it can often help fix bugs and program errors.

These 15 tips can help developers create code and programs more efficiently and at a much faster pace. Also minimize bugs and errors that occur during encoding.
