This is a fast paced workshop, which will enable experienced developers to:

  • Write Object Oriented and Functional code in JavaScript
  • Take advantage of the new features in ES6 and Typescript
  • Use modern tools such as WebStorm, Babel and WebPack
  • Create basic Web Applications via Angular and React


The workshop is delivered over three days, with the majority of the time spent on exercises and practical work. WebStorm is the default IDE, with WebPack and Babel used to transpile ES6 and TypeScript. Delegates must be experienced Java or C# developers who are already familiar with HTML, CSS and REST. Previous experience of JavaScript is advantageous but not required.


Workshop Modules

Basic JavaScript Programming

  • The core JavaScript types and dynamic typing
  • Explicit and implicit variable declarations
  • Implicit conversions and the bugs they can cause
  • Minimizing your programs use of global variables
  • Using typeof and instanceof to investigate types
  • The lack of block scope and ‘variable hoisting’
  • Understanding truth and equality in JavaScript
  • Making choices, basic iteration and the for…in loop
  • Manipulating strings and applying regular expressions
  • Working with single and multi-dimensional arrays
  • The difference between arrays and ‘array-like’ objects

Writing Functions in JavaScript Part 1

  • How and why functions are ‘first class citizens’
  • Four patterns of invocation for calling JavaScript functions
  • Understanding how the binding of this varies in functions
  • Calling functions with fewer parameters or additional ones

  • Building and returning functions from functions

Writing Functions in JavaScript Part 2

  • Using generated functions as closures
  • Why closures store references to outer variables
  • Subtle bugs caused by incorrect use of closures
  • Using nested functions as an encapsulation technique
  • The ‘immediately invoked function expression'(IIFE)

Functional Programming with ‘Underscore.js’

  • Using functions as the unit of composition
  • Replacing external iteration with each, filter and map
  • Producing a single value from a list via folds and reductions
  • Applying currying and partial application in JavaScript

Object Orientation in JavaScript Part 1

  • Understanding the prototype based style of OO
  • Pros and cons of ‘monkey patching’ types
  • Declaring objects using the Object type

  • Declaring objects using constructor functions
  • Protecting against incorrect constructor invocation
  • Different options for accessing members of objects

Object Orientation in JavaScript Part 2

  • Implementing inheritance using the prototype chain
  • Distinguishing between owned and inherited properties
  • The difference between prototype and __proto__
  • Minimizing mutable state when designing JavaScript types
  • Applying the SOLID principles of OO design in JavaScript

Taking Advantage of ES6

  • Writing modern JavaScript and retaining compatibility
  • Understand modules and support for import / export
  • Interpolation via template literals and back-tick quotes
  • Using the ‘let’ keyword to declare block scopes
  • Iterators, generators and the ‘for..of’ statement
  • The new class syntax for declaring types and properties
  • Using the spread operator with functions and structures
  • New data structures (maps, typed arrays, promises etc)
  • Simplified functional programming with arrows

Taking Advantage of TypeScript

  • Why do we need TypeScript?
  • Introduction to Babel and Webpack
  • Support for TS in the WebStorm IDE

Getting Started with React and Redux

  • Initializing a new project via ‘create-react-app’
  • Using JSX to combine markup with JavaScript
  • Four different ways to code a new component
  • Using properties to pass data into components
  • Initializing and altering the state of a component
  • Making use of the component lifecycle callbacks
