# Coding Standards

## 1. Meaningful variable names, file names, folder names. Use abbreviations for words over ten characters. Abbreviations must be over three characters.

- ✅ `update-btn` (refresh button), `device-list`, `user-profile-settings` (profile = abbreviation)
- ❌ `btn` (too vague), `d1` (meaningless), `temp` (unclear), `us` (abbreviation too short)

## 2. Use hyphens (`-`) for multi-word names.

## 3. Comments: One Function, One Comment, English Only

## 4. Use functions to separate different logic. Avoid writing too much logic in a single function.

## 5. Never use try-catch. Let errors crash.

## 6. GUI components must split into three files:

- `.jsx`: Layout only (no logic, no styles)
- `.js`: Logic only (functions, state, business logic)
- `.scss`: Styles only (no logic, no JSX)

**Never write logic or inline styles in `.jsx` files.**

## 7. Use the least code to implement functionality. 

## 8. Do not add any `console.log` statements in production code.

## 9. Do not create script files unnecessarily. If you can call PowerShell directly, use PowerShell instead of creating a separate script file.

## 10. If you need to create any new files, you must ask first.

## 11. Use `switch` statements instead of multiple `if-else` chains when checking the same variable against multiple values.

## 12. Prefer Early Return Over Else Blocks

Prefer early return pattern:
```javascript
if (condition) { 
    ...
    return;
}
```

Instead of:
```javascript
if (condition) {
    ...
} else {
    ...
}
```

## 13. No Existence Checks

Do not add if statements to check if directories exist, files exist, or if parsing succeeded. Let errors crash.
