In this issue, the editor will bring you about the web development and programming skills that every developer should know in 2021. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

With the development of the software industry, the demand for senior developers is increasing, but with the increasing demand, good programmers are becoming more and more scarce.

Technology is endless, whether you are an experienced programmer or a new programmer, as a modern developer, you should know how to integrate modern technology and other technical knowledge to make yourself an expert in the field of expertise.

If you want your resume to be better than other interview competitors, you can test yourself to see if you have mastered all of the following skills, and if not, these are skills you will learn in 2021:

1. Data structure and algorithm

In most large technology companies, this skill is a top priority, and good software developers should know how to use data structures and algorithms and how to use them to solve practical problems.

Data structures and algorithms are the core of programming, and they must not be underestimated when programming. Here are some resources for learning data structures and algorithms:

Stanford Coursera course: https://www.coursera.org/specializations/algorithms

MIT YouTube course: https://www.youtube.com/watch?v=HtSuA80QTyo&list=PLUl4u3cNGP61Oq3tWYp6V_F-5jb5L2iHb

A book that comprehensively describes the necessary knowledge of algorithms and data structures.

In software development, the use of data structures and algorithms can greatly improve programming efficiency, you can learn from HackerEarth, GeeksforGeeks, Hackerrank, LeetCode, InterviewBit and other websites.

two。 Programming language

To be a good programmer, you must have an in-depth knowledge of at least one programming language, depending on your area of interest and your own love of programming. You can learn online programming language courses from Udemy,Coursera and other online platforms.

3. Database and SQL

Database is the core of any program you write. For today's developers, database is an essential skill. Database is an effective way to keep the data of software companies organized and secure. Through it, you can easily retrieve data and prevent unauthorized access. SQL is the most popular classic database among developers.

SQL can basically help solve many problems, especially when dealing with a large amount of data, it is also an intuitive query language, with high requirements, of course, you also have Redis,Oracle,PostgreSQL,Cassandra and so on.

4. IDE (integrated development environment)

According to Wikipedia, "IDE is a software application that provides the application of the program development environment, integrating coding, analysis, compilation, debugging and other functions." In short, IDE is one of the most basic tools needed to write code effectively.

Every programmer or developer must know how to use IDE to write, compile, run, and debug their code. Using IDE can speed up their work, and there are many IDE options that developers can choose, and the most recommended choice for C, C++, and C # programmers is Visual Studio or Code:: Blocks. For Python developers, it is recommended to choose PyCharm or Jupyter Notebook.

5. Network foundation

For today's developers, it is important to understand the basic knowledge of the network, especially when we live in a world of network connections, wherever we go, we can find Wi-Fi, and there are interconnected networks everywhere.

Most developers' work is based on the client-server model, where requests reach the server through the network, and the client can access it anywhere. Today, the client-server architecture has been used in most applications, such as Web-based, online games or business automation.

6. Source code control

In software engineering, source code control (version control) is a system responsible for managing changes to computer programs, documents, large websites, or other collections of information.

In short, version control is a way to store code that helps developers track and manage code changes. to be a good software developer, you must know how to manage the version of the code you write, how to create code branches, and learn to use version control tools such as Git (70-80% of enterprises preferred), and of course you can choose Mercurial,SVN and so on.

7. Script language

Not all script scripts are considered programming languages, and vice versa. In fact, the boundaries between programming languages and scripting languages are not very clear.

The difference between scripting and programming languages is that scripting languages do not require compilation steps, for example, C programs need to be compiled before running, while scripting languages such as JavaScript or PHP are usually not required. There are other scripting languages that are the same with Perl,Ruby,Python.

But why do we need to learn them? Many scripting languages are used to design and develop the front end of Web applications, and if you are a Java programmer or Java programmer, it will be difficult for you to work as efficiently as a Python or Perl developer.

8. Cryptography

When creating software or Web applications, it is important for developers to implement secure and encrypted keys to maintain user privacy and prevent various attacks.

Encryption is important because it enables developers to securely protect data that they do not want others to access. After the data is encrypted, only the authorized party with the "key" can read or use it.

According to the Software Alliance (Software Alliance), cyber criminals stole 423 million identities in 2015, and the longer the data is lost, the greater the threat to data security. With such a large amount of data, encryption is an absolute necessary condition for privacy and security.

These are the web programming skills that every developer should know in 2021. If you happen to have similar doubts, please refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
