# Juniors Best Practice

Juniors-focused best practices for React and TypeScript projects. The rules are short, practical, and organized by scope to guide consistent code reviews, refactoring, and new feature work.

## When to Apply

Reference these guidelines when:
- Writing or reviewing React/TypeScript code for clarity and consistency
- Teaching junior developers or establishing baseline team conventions
- Refactoring code to align with simple, maintainable patterns
- Standardizing project-wide practices (imports, tooling, naming, commits)

## Rule Categories by Priority

| Priority | Category | Impact | Prefix |
|----------|----------|--------|--------|
| 1 | Beginner Foundations | HIGH | `beginner-` |
| 2 | TypeScript | MEDIUM | `typescript-` |
| 3 | React | MEDIUM | `react-` |
| 4 | Styling | MEDIUM | `styling-` |
| 5 | Devtools | MEDIUM | `devtools-` |
| 6 | Assets | LOW-MEDIUM | `assets-` |
| 7 | Git | LOW | `git-` |

## Quick Reference

### 1. Beginner Foundations (HIGH)
- `beginner-early-return` - Prefer early returns to reduce nesting
- `beginner-double-negation` - Avoid `!isNotX` patterns
- `beginner-unnecessary-destructuring` - Keep objects intact for clarity
- `beginner-const-vs-let` - Default to const
- `beginner-nullish-vs-or` - Use ?? for defaults
- `beginner-useless-return-arrow` - Remove redundant return
- `beginner-uppercase-constants` - Use UPPER_CASE only for stable constants

### 2. TypeScript (MEDIUM)
- `typescript-alias-naming` - Use safe path alias prefixes

### 3. React (MEDIUM)
- `react-string-props` - Use string literals when possible
- `react-children-prop` - Use children for composition
- `react-extends-component` - Extend native element props
- `react-props-typing` - Keep props typing readable

### 4. Styling (MEDIUM)
- `styling-classnames-function` - Use clsx for conditional classes
- `styling-css-states` - Prefer CSS selectors for component states

### 5. Devtools (MEDIUM)
- `devtools-formatter-linter` - Use formatter and linter
- `devtools-sorting-imports` - Keep imports ordered and grouped
- `devtools-package-manager-lock` - Use a single package manager

### 6. Assets (LOW-MEDIUM)
- `assets-svg-files` - Use SVGs as components

### 7. Git (LOW)
- `git-commit-convention` - Use consistent commit conventions

## How to Use

Read individual rule files for detailed explanations and examples:

```
rules/beginner-early-return.md
rules/react-props-typing.md
```

Each rule file contains:
- Brief explanation of why it matters
- Incorrect code example with explanation
- Correct code example with explanation
- Additional context and references
