The purpose of using local variables in the ENGLISH_CALC function is to limit the scope of those variables to the function itself. This means that local variables can only be accessed and modified within the function, preventing any unintended interference with global variables or other parts of the script.
Using local variables helps to:
- Avoid Naming Conflicts: Local variables can have the same name as global variables without causing conflicts.
- Encapsulate Function Logic: It keeps the function self-contained, making it easier to understand and maintain.
- Prevent Side Effects: Changes to local variables do not affect the global state, reducing the risk of bugs.
In summary, local variables enhance modularity and maintainability in your code.
