The title may be a bit misleading: the answer to the question "to teach or not to teach" is not as clear-cut as it seems. Our respondents were divided into four groups with different opinions and approaches to learning.

• Some boldly assert that you can feel confident in IT without a degree in Computer Science.
• Others say you can start even if you are a complete novice in computer science. But later, you'll still have to catch up on your theoretical knowledge.
• Others insist that without a solid background in Computer Science, it's not even worth entering the profession.
• Finally, others approached the issue from a purely practical perspective: Computer Science is a global science, not understood by everyone. Therefore, there is no need to try to embrace the immensity: each specialty has its own specific section of CS.

We suggest you hear all points of view and, based on this, make an informed choice that will be closest to you.

Those who can't play rehearse

Principal Frontend Developer and CTO at CSSSR. A specialist with deep knowledge of frontend development and team management. Experienced in creating high-quality web applications and implementing modern technologies. Actively involved in developing strategies to improve user experience and optimize development processes. Focused on implementing best practices and standards in teamwork, which allows for increasing the efficiency and quality of the final product. CSSSR is a company known for its innovative approach and commitment to cutting-edge technologies in the field of web development.

A beginner developer does not need to delve into the basics of Computer Science. If they are not familiar with the Hindley-Milner type system, this will not be an obstacle to their work. Moreover, they can use this system at the application level without even realizing it. At the initial stage of a career, a beginner is most often engaged in craftsmanship, and only approaches engineering activities later. It's a natural progression that allows you to gradually accumulate knowledge and experience in programming.

In my opinion, Computer Science is more focused on theoretical research and scientific aspects than on everyday practice. However, the development and practical application of technologies also play a significant role in this area.

A Principal Frontend Developer at CSSSR is responsible for the development and implementation of high-quality user interfaces. This key role involves not only writing clean and efficient code but also coordinating a team of front-end developers. Key responsibilities include designing application architecture, optimizing interface performance, and ensuring cross-browser compatibility. Collaborating with designers and back-end developers to create functional and aesthetically pleasing solutions is also crucial. The position requires a deep knowledge of modern technologies such as JavaScript, HTML, and CSS, as well as experience with frameworks and libraries such as React or Vue.js. CSSSR offers opportunities for professional growth and participation in interesting projects, making this position attractive to experienced front-end developers. Provocative statement: Computer science is not required for most developers working in practical applications. There are exceptions where specific knowledge in certain areas is necessary, but in such cases, it is more practical to focus on studying specific topics rather than delving into general computer science theory. This allows developers to more effectively solve real-world problems without being distracted by theoretical aspects that may not be directly relevant to their work.

Does this mean that computer science is invaluable? No, it's not. A developer's professionalism is determined not only by skills in specific technologies and problem types. Knowing a multitude of patterns and libraries won't make you an experienced specialist unless it's backed by a culture of engineering thinking. Without this culture, you will face difficulties solving non-standard problems and creating innovative solutions. Engineering thinking allows you to analyze problems from different angles, find optimal approaches, and adapt to new conditions. Thus, computer science plays an important role in developing the skills necessary for a successful career in IT.

Practice is one of the most effective learning methods. However, this approach has its drawbacks: the learning process can take a long time and is not always controllable. We often don't know what problems we'll face, and we don't always have the opportunity to choose them ourselves.

The main value of Computer Science is that it aggregates complex problems that arise during the development of programming in their original form. Unlike other fields, there are no overlaying frameworks or external system APIs, allowing for a deeper understanding of fundamental principles and algorithms. This enables developers and researchers to better understand programming fundamentals and create more effective solutions based on clean and understandable code.

Rote memorization is pointless, since in real work you won't encounter identical abstract problems unrelated to specific technologies. Practical skills remain indispensable, and only a combination of theory and practice can lead to effective learning and professional growth. Theoretical knowledge and practical experience complement each other, creating a solid foundation for success in any field.

I programmed for a long time without basic computer science knowledge, and the results were not very good. Now that I have mastered some theoretical foundations, I have improved the quality of my code. Constant optimization and the search for effective solutions contribute to the development of my skills. I no longer resort to brute-force solutions to iterate over arrays.

Basic knowledge of computer science significantly facilitates problem solving. By mastering basic data structures, algorithmic patterns, and approaches, you can analyze problems faster, find optimal algorithms, and implement them effectively. This, in turn, contributes to the improvement of the quality of decisions made and an increase in overall productivity at work.

If you work with high-load applications, develop a core component, or optimize a system to handle millions of requests per second, knowledge of the basics of computer science becomes essential. Understanding efficient algorithms and data structures is critical, as an inefficient loop or poorly chosen structure can significantly increase execution time, which in turn leads to a significant increase in CPU consumption. In a large-scale infrastructure, this can lead to the need for additional servers, significantly increasing costs.

Learning to program is truly challenging and requires a significant time investment. The ultimate benefit of learning isn't always clear. If you're lucky enough to attend a university that provides quality instruction, provides examples, and helps you understand complex concepts, that's a huge plus. However, such institutions are rare. Students can often spend years working on simple tasks like processing CRUD operations and working with JSON without delving into the deeper aspects of computer science, and this is also a normal part of learning. It's important to understand that even basic skills can lay the foundation for further advancement in IT.

For professional growth, it's important to actively develop your skills by taking on tasks in your current position and gradually expanding your proficiency. If you have the opportunity to attend university concurrently, this will be a major advantage. You should also consider taking courses or watching tutorials to expand your knowledge and skills.

There is a belief that to succeed in Computer Science, you need to immerse yourself in the topic at the deepest level possible. Otherwise, according to some, a programmer risks becoming a "pathetic coder," a "form-slapper," or simply a "Jason-shifter." However, I disagree with this point of view. Sometimes working with data, even at the level of a "Jason-shifter," requires significant knowledge and skills. It's important to understand that every programming role, no matter how complex, plays a significant role in developing and supporting software solutions.

There are people in the programming field who didn't study computer science but started their careers as junior developers and even reached mid-level positions. They have a stable income and don't seek additional training. I've worked with such colleagues and sometimes noticed that they struggle to solve problems that might seem simple. Often, their approaches resemble reinventing the wheel, even though ready-made solutions have long existed. I recommend them to familiarize themselves with the "Chinese Room" thought experiment. Without a deep knowledge of computer science, you can end up in a situation where your framework becomes like this room: everything works well on standard tasks, but any deviation from the usual path causes confusion and difficulty.

I adhere to the opinion that a happy medium is necessary when studying computer science. It's important to start with the basic concepts to avoid overloading yourself with complex information and a large amount of knowledge that may not be relevant to your current goals.

• What do you prefer: front-end, back-end, game development, mobile, or something more narrow and specific (neural networks, high-load systems, computer security).

If you haven't yet made a choice, it's helpful to explore and try different areas to find the right one. Having a clear idea of ​​your interests will allow you to focus on the necessary knowledge. Even if you later decide to change direction, the skills you've learned will prove useful in the future.

Each programming field requires mastering a specific set of languages, tools, and theoretical foundations. However, there are also universal skills that will be useful regardless of your chosen specialization.

If you want to work in front-end development, there's no need to delve into low-level technologies. Focus on understanding UI/UX and design, as well as being proficient in JavaScript, CSS, and modern frameworks. This knowledge will allow you to create high-quality, user-friendly interfaces, which is key to a successful career in front-end development.

If your goal is computer security or developing multithreaded, high-performance applications, a deep understanding of processor and operating system design is essential. Understanding these aspects is key to working effectively in these fields, as they ensure performance optimization and software security.

Game development involves a number of key components, such as game engines, trigonometry, vectors, matrices, and shaders. These elements play a vital role in creating an engaging gaming experience. Developing the backend of online services requires knowledge of databases, networking technologies, and other specific aspects that ensure the stable operation and security of the application. Understanding these technologies is crucial for the successful implementation of projects in game development and web development.

Regardless of the chosen programming direction, it is important to have a clear understanding of basic data structures and algorithms. Over time, it is also worth mastering design patterns. When learning programming languages, it is recommended to focus on key libraries and frameworks to avoid reinventing the wheel. For example, for C++, these might include STL, Boost, and Qt. A good command of tools, such as development environments, debuggers, package managers, and version control systems, also greatly simplifies the work. These skills will help increase development efficiency and improve code quality.

Knowledge of English, at least at the level of reading technical literature, is essential for a successful career in IT. Without this skill, working with documentation and modern technologies will be extremely difficult. It is also important for every programmer to have a basic understanding of computer design and operating systems. Understanding all other aspects of the profession comes with experience, so don't try to master everything at once. IT is a dynamically developing field, and to succeed in it, you must be prepared for constant learning and practice. A genuine interest in the industry will help you overcome all difficulties along the way.

Theory without practice is meaningless and quickly fades from memory. Therefore, it is critical to write code regularly. Find an interesting project and implement it yourself. Gradually add new features, improve the code and architecture – this will be an excellent training ground for you. Practical application of knowledge will help reinforce theoretical foundations and develop programming skills.

There are many communities, such as Telegram chats, Stack Overflow, and specialized forums, where you can find like-minded people. These platforms provide an opportunity to get help solving various difficulties and find answers to your questions. Don't be afraid to ask questions, even if they seem simple or insignificant. Communicating with experienced community members will help you quickly understand complex topics and develop your skills.

I wish all beginners inspiration and success in their endeavors! May every step along this path be filled with enthusiasm and a desire to develop.
