JavaScript/TypeScript Coding Standards

When reviewing or generating JavaScript/TypeScript code, follow these rules:

File Naming

• Source files: Use kebab-case (e.g., user-service.js, api-client.ts)
• Component files: Use kebab-case (e.g., user-profile.js, data-table.tsx)
• Test files: Use .test.js or .spec.js suffix (e.g., user-service.test.js)
• Type definition files: Use .d.ts suffix (e.g., api-types.d.ts)

Variable Naming

• Variables: camelCase (e.g., userName, isActive, totalCount)
• Constants: UPPER_SNAKE_CASE for true constants (e.g., MAX_RETRIES, API_BASE_URL)
• Boolean variables: Prefix with is, has, can, should (e.g., isLoading, hasError)
