Phase 5 — Modern JavaScript

Modern JavaScript (ES6 and beyond) introduced powerful features that make code more expressive, concise, and maintainable. This phase covers template literals, destructuring, functional programming patterns, BigInt, dynamic imports, and more.

  • Use template literals, destructuring, and spread/rest effectively
  • Understand functional programming concepts (currying, composition)
  • Work with BigInt for large integers
  • Use dynamic imports for code splitting
  • Phase 1 — Fundamentals
  • Phase 2 — Core Concepts
TopicDescription
ES6+ OverviewMajor ES6/ES7/ES8/ES9/ES10+ features timeline
Template LiteralsString interpolation, multiline, tagged templates
DestructuringArray and object destructuring patterns
Spread/RestSpread operator, rest parameters (covered in Phase 1)
Dynamic ImportLazy loading modules on demand
Functional ProgrammingPure functions, immutability, declarative style
CurryingTransforming multi-argument functions
CompositionCombining functions (compose/pipe)
Optional ChainingSafe nested access (covered in Phase 1)
Nullish CoalescingDefault values for null/undefined (covered in Phase 1)
BigIntLarge integer arithmetic
SymbolUnique identifiers (covered in Phase 2)
