8 concepts that are worth learning for a novice programmer

Preamble

​​In this article, there are 8 concepts to understand if you want to become an advanced programmer faster. The list is not complete, but it can be a good starting point for self-education in development. Learning programming languages is implied by default. 

Data structures and algorithms

It isn’t easy to write an application without knowledge of basic data structures (arrays, linked lists, hash tables, etc.). It is one of the essential topics in an interview. Many boot camps of programmers teach you data structures and algorithms in the first place.

Version control system Git

Git helps to store and modify code and makes team development convenient. When several developers write a single project, the version control system allows them to make changes in parallel without overwriting each other or creating conflicts.

Git is not the only version control system, but most companies and projects use it, so we recommend giving it your preference. Git has both graphical interfaces and a command line to work with. The choice is yours.

Text editors and IDE

The text editor is an essential assistant for any IT user.

NotePad on Windows and Vim on Linux are popular tools for tasks in development. There is also a wide range of editors with advanced features (e.g., Sublime and NotePad ++), which provide a quality set similar to the actual IDE.

Development in editors requires a lot of independent actions: it is necessary to save files, compile, build, etc., separately. It is helpful for a better understanding of the computer but slows down the development process a lot. The programming approach has entirely changed with the IDE – integrated development environments. They combine and automate most of the necessary functions from the first line of code to the project release. It will be helpful to spend time learning the hotkeys.

Databases and SQL for a novice programmer

SQL is a classic and precious tool. It has existed for over 30 years and will be famous among developers for a long time. A wide range of database applications implies that the programmer will be expected to have basic knowledge in this area.

In the same way, many databases: Oracle, Microsoft SQL Server, MySQL, PostgreSQL, and others. Also, but for starters, it will be enough to know only the key points: insert/update/delete data and write SQL queries.

Nowadays, NoSQL solutions are becoming more and more popular in large-scale distributed projects, where data storage and access are arranged differently. If you’re beginning to study the database, we recommend first dealing with the relational approach and then learning NoSQL.

Command-line

There are many operating systems and even more graphical shells to work with. UI is a convenient way to interact with the system. Still, good command-line knowledge will allow one to interact effectively with the computer at a lower level and thus have more control. You will be able to monitor the system more closely and perform all basic or only auxiliary tasks.

Microsoft Excel

Excel in this list is not accidental. Programmers, developers, managers, traders, and businesspeople use it. 

It’s not just a spreadsheet program. Excel has many essential features for data reconciliation and analysis, project tracking, and planning. It allows not only to copy and paste data but also to perform basic data manipulations (search, sorting, filtering, etc.).

Basics of computer networks

Many existing mobile or web applications are not standalone but client-server applications. Users access the service from anywhere in the world. Understanding the fundamentals of dealing with networks is required to design and support such applications.

Scripting languages

You can, of course, use the same language for both OOP and scripting. But any language is not suitable for it. If you have to work with C/C++ or Java, you can get as fast a result as Python developers can.

The scripting language makes it easy to create tools and scripts to solve typical problems. If you know this language well, you can easily automate routine things.
