Coding Style

Immutability (CRITICAL)

ALWAYS create new objects, NEVER mutate:

// WRONG: Mutation
function updateUser(user, name) {
  user.name = name  // MUTATION!
  return user
}

// CORRECT: Immutability
function updateUser(user, name) {
  return {
    ...user,
    name
  }
}

File Organization

MANY SMALL FILES > FEW LARGE FILES:

  • High cohesion, low coupling
  • 200-400 lines typical, 800 max
  • Extract utilities from large components
  • Organize by feature/domain, not by type

Error Handling

ALWAYS handle errors comprehensively:

try {
  const result = await riskyOperation()
  return result
} catch (error) {
  console.error('Operation failed:', error)
  throw new Error('Detailed user-friendly message')
}

Input Validation

ALWAYS validate user input:

import { z } from 'zod'

const schema = z.object({
  email: z.string().email(),
  age: z.number().int().min(0).max(150)
})

const validated = schema.parse(input)

Code Quality Checklist

Before marking work complete:

  • Code is readable and well-named
  • Functions are small (<50 lines)
  • Files are focused (<800 lines)
  • No deep nesting (>4 levels)
  • Proper error handling
  • No console.log statements
  • No hardcoded values
  • No mutation (immutable patterns used)
