Top 10 things Programmers must know in 2021

If you have been self-teaching programming to yourself and wondering what are some of the most basic things every software developer or programmer should learn or know, then, here is a list of some of the fundamental things you can learn to do well as a programmer. If you are having fair share of programming or into the field of coding, you would have tried to get better with latest technologies and trends.


Simply learning coding is not a door of success for every programmer. Apart from coding, there are lot more other things that every newbie or experienced programmer should be aware of. This list is by no means complete and I have not included some of the more advanced things like regular expression but it does provide you a good starting point for things a programmer should know.


10 Key Skills every Programmer should know in 2021


1. Understand your Customer’s Business

The first item on this list applies to any business: know your customer. You can’t design and deploy great software without understanding its purpose, use case, or end-user.

“If you don’t know the WHAT, you can’t decide the HOW”.

Understanding how your customer’s business operates and what they hope to achieve means you’ll start the project with better requirements, design, and a framework for implementation and testing. In turn, it enables you to create business value.


2. Communication

Communication processes can make or break the success of any development effort. A programmer/software engineer isn’t responsible for the entire project. Each team member has their own set of tasks, making communication essential for delivering a cohesive final product.

Even if you receive a minor change request in an informal discussion, it is still advisable to put these changes through official channels to inform everybody about these changes and document them for future use.


3. Programming Languages and Scripting

Programming and scripting languages seem like things every software engineer should know. As a programmer or software engineer, you must have familiarity with programming languages. Often, experience with a single programming language won’t get you very far. If you want to open the door to better opportunities, develop expertise in multiple coding languages such as Java, Python, C++, JavaScript, etc.


4. Database and SQL

Database is the heart of any program you write! It is essential that you are aware about database concepts and its use in programming. There are plenty of different databases available in the market, but it is not necessary you know all. If you are aware about only one of them, it is enough to survive as a programmer. It is important that you know how you can perform CRUD operations in SQL or any other database.


5. Cloud Computing

Cloud computing has become standard for businesses of all shapes and sizes. That means it’s now a basic competency for any software engineer or programmer. In recent years, organizations were moving their systems to the cloud in large numbers, due to its many advantages, including:

§  Increased security.

§  Reduced cost.

§  Improved scalability.

§  Ease of deployment.

§  Improved flexibility.


6. Source Controls

Source control is another concept every programmer should know. The term refers to the practice of tracking and managing code changes. The idea is, you’ll have a real-time log documenting the code development process, allowing for fast conflict resolution when merging contributions from multiple sources.

Source control also improves the development process by allowing different teams to work in parallel. Because you can work with a copy of the main repository, there’s no need to modify the original codebase.


7. Networking Basics

Being a programmer, you might be developing applications involving client-server interaction to perform various activities. It is important that you are aware about basic networking fundamentals like TCP-IP, Network packets, Linux command and more.


8. Basic Project Management Skills


Working with project managers, scrum masters, or technical leads could present some challenges if you’re not familiar with the terminology and processes that define your workflow. Learning the basic concepts of project management makes it easier to work on teams and organize your own tasks. These concepts can help you identify who is responsible for each task and what role each team member should assume.


9. Save Your Code Changes Constantly


Many programmers learn this lesson the hard way–continuous backups will save you from a lot of pain. Often, developers get caught up in the process and forget to save changes. Plus, there are times when the system fails, undoing all that hard work. Even saving every few minutes isn’t always enough. Look toward cloud-based solutions that automatically backup changes to avoid potential rework.


10. Keep Learning

Finally, the most important thing every programmer should know is that the learning process never ends. There’s always something new to learn, whether that’s mastering a new programming language, sharpening your cybersecurity skills, or embracing innovations like augmented reality, the IoT, or edge computing. Technology runs faster than we do, and every programmer should know that success hinges on their ability to adapt–or else they’ll become obsolete.


Becoming a good programmer is not a kid’s toy! It requires lot of efforts in learning and mastering essential aspects mentioned in this blog. Good knowledge of these skills goes a long way in your programming career because you will use these skills each and every day and appreciate the time and effort you put initially to learn them..
