Unless you have a great IDE, you probably will never know the mistakes that made in your code. Not all software development teams prefer to have a Testing or Quality Assurance department. “67 percent of app users cite bad experiences as a reason for churn,” says a stat from TestLio.
Bad experiences are mainly a result of bugs and errors caused during production. As a programmer, it is imperative that you fix the common mistakes that most other programmers make. In this post, I have shared a few flaws most people in your position make.
Here Are the 5 Mistakes Most Programmers Make Without Knowing About It
1) Not Breaking Things Down
Most beginner programmers fail to break the whole logic down into small easily understandable chunks of sections. They try to jam everything into one class file or a method. Languages like Java and PHP allows you to create several inheritable classes and interfaces. It is recommended to dry run the code on a piece of paper or a notepad file first and then come up with the best strategy to write the final code.
2) Not Attempting to Solve the Problem by Themselves
Programming forums like StackOverflow, the Official Microsoft ASP.NET Site, StackExchange, and TreeHouse are great as they offer you support and guidance for free. However, most programmers abuse these forums and turn to them every time they need a quick solution to a programming problem.
Surely, by posting your problem online someone will give you their perspective; which will help you understand the problem even better. However, it is always a good idea to use your brain first.
3) Not Giving Meaningful Names to Variables and Methods
No matter which programming language you work with, you will have to use variables, methods, and classes. It is very common for beginners to name them without knowing their role from the context of the application or the project.
Naming a variable with letters (a, b, c, etc) or meaningless words (ABC, XYZ, etc) makes the code unreadable for other programmers; and also yourself. Always understand the true function of the variable or a method first and name it accordingly.
4) Hard Coding the Values
Don’t get me wrong. I understand that in some instances, it is necessary to assign a fixed value to a variable. However, hardcoding the variable without thinking about its ramifications can land you in trouble during the testing phase. Unless the application demands you to hard code a value, always keep the code flexible by using the correct data type (like int, byte, long, etc).
5) Not Using Version Control Systems
This is not a problem specific to a programmer but in general, it is always recommended to use a Version Control System like Tortise or Github. Most Version Control Systems are available for free of cost. You can also have your code save offline on your personal or work computer. It keeps track of all the changes made in the project by you and your teammates.
Most software professionals are thrown in an incredibly fast-paced environment where everyone is doing their best to get ahead. Hence, it is essential that you don’t get too complacent by neglecting the mistakes you make.
