Essential skills for programmers:

1. Proficient in development tools

As a programmer, you must be proficient in the use of at least two to three development tools. This is the foundation of a programmer.

You need to master basic scripting languages, such as shell, perl, etc., and at least be able to read these script codes.

2. Familiar with databases

Programmers must be proficient in at least one or two databases, must be very clear about the key elements of relational databases, and must be proficient in the basic syntax of SQL.

3. Understand the operating system

If you want to become a true programming master, you need to have an in-depth understanding of the operating system, its memory management mechanism, process/thread scheduling, signals, kernel objects, and system Calling, protocol stack implementation, etc.

4. Requirements understanding ability

Programmers must be able to correctly understand the requirements described in the task order. It should be clear here that programmers should not only pay attention to the functional requirements of the software, but also the performance requirements of the software.

You must be able to correctly evaluate the impact and potential threats of your own modules on the entire project. If a skilled programmer with two to three years of project experience does not understand this, it can only mean that he may be serious. I worked, but I didn’t work hard.

5. Modular thinking ability

As an excellent programmer, his thinking cannot be limited to the current work tasks. He must think about whether the modules he writes can be separated from the current system. It exists and can be used directly in other systems or other modules through simple encapsulation.

This can make the code reusable, reduce duplication of labor, and make the system structure more reasonable. The improvement of modular thinking ability is an important indicator of the improvement of a programmer's technical level.
