JavaScript Deep Dive: Modern ES6+ Techniques
Programming

Course Description


This intensive 3-day course explores modern JavaScript (ES6 and beyond) to equip developers with the latest language features and best practices. From arrow functions and destructuring to modules, promises, async/await, and advanced patterns, learners will deepen their understanding and write cleaner, more efficient, and maintainable JavaScript code.


Duration: 3 Days

Format: Instructor-led workshops, hands-on coding, and real-world examples

Course Outline


? Day 1: ES6 Syntax and Core Features

Session 1: Let, Const, and Block Scope


  • Differences between var, let, and const
  • Temporal dead zone and hoisting
  • Scope and closures refresher


Session 2: Arrow Functions and Enhanced Functions


  • Arrow function syntax and behavior
  • Default parameters, rest and spread operators
  • Function expressions vs declarations


Session 3: Destructuring and Template Literals


  • Array and object destructuring
  • Nested destructuring and default values
  • Template literals and tagged templates


Lab Activities:


  • Refactor ES5 code using let/const and arrow functions
  • Use destructuring for function parameters and objects
  • Build dynamic strings with template literals


? Day 2: Modern Objects, Classes, and Modules

Session 1: Enhanced Object Literals and Symbols


  • Property shorthand and method definitions
  • Computed property names
  • Symbol type and well-known symbols


Session 2: Classes and Inheritance


  • Class syntax and constructors
  • Inheritance with extends and super
  • Static methods and getters/setters


Session 3: Modules and Import/Export


  • ES6 module syntax
  • Named and default exports
  • Dynamic imports and code splitting basics


Lab Activities:


  • Create classes with inheritance and encapsulation
  • Organize code into modules and practice imports/exports
  • Use symbols for private properties and custom iterators


? Day 3: Asynchronous JavaScript and Advanced Patterns

Session 1: Promises and Async/Await


  • Promise creation and chaining
  • Error handling in promises
  • Async functions and awaiting results


Session 2: Iterators, Generators, and Async Iterators


  • Understanding iterators and the iterator protocol
  • Generator functions and yield keyword
  • Async iterators and for-await-of loops


Session 3: Advanced Patterns and Best Practices


  • Proxy and Reflect APIs
  • WeakMap and WeakSet
  • Functional programming concepts in modern JS


Lab Activities:


  • Write async code using promises and async/await
