As programmers, variable naming should be the beginning of our programming, and it is something we must do every day. The importance of variable naming conventions, I believe everyone knows it is very important, good code style, the benefits are:

1. Good readability;

2. It is also clearer and easier to maintain the code;

3. Facilitate handover and communication with the team and others.

For beginners, it is very common for variables to be named too casually or not to know what rules to follow . So, today I recommend one to everyone: the variable naming artifact .
