What are some common mistakes people make with system variables?

Some common mistakes include not initializing variables, using incorrect data types, and failing to scope variables properly.

Can you give me an example of a mistake with variable initialization?

Sure! A common mistake is trying to use a variable before it has been assigned a value, which can lead to errors.

What about data types? How can that be a mistake?

Using the wrong data type can cause unexpected behavior, like trying to perform arithmetic on a string instead of a number.

How can I avoid these mistakes?

You can avoid these mistakes by thoroughly testing your code, using linters, and following best practices for variable management.
