Introduction to ECMAScript 6 (ES6)

Core ES6 Scripting and Development Skills for Modern Web Developers



2 Days

Course Overview

ECMAScript 6 is the new edition to the ECMAScript language, whose specifications are inherited by JavaScript. ES6 gives a vast makeover to JavaScript by adding new syntaxes and APIs to write complex applications and libraries that are easier to debug and maintain. By learning the latest version of ECMAScript, you'll have a greater understanding of JavaScript and more confidence and fluency when developing with it - follow this course and use and adopt ES6 features into your work, instead of the usual tired JavaScript hacks and tricks.

JumpStart to ECMAScript 6 (ES6) introduces students to ECMAScript 6's built-in objects and shows them how to create custom Iterators.  It also provides guidance on Next, as well as how to write asynchronous code in a synchronous style using ES6, so developers can unlock greater control and sophistication in the way they develop with JavaScript.

Beyond this, students will also explore how to learn how to use Reflect API to inspect and manipulate object properties. Next, it teaches how to create proxies, and use it to intercept and customize operations performed on objects. Finally, it explains old modular programming techniques such as IIFE, CommonJS, AMD, and UMD and also compares it with ECMAScript modules and demonstrates how modules can increase the performance of websites when used.

Course Objectives

Our engaging instructors and mentors are highly experienced practitioners who bring years of current "on-the-job" experience into every classroom. Working in a hands-on learning environment, guided by our expert team, attendees will learn about and explore:

  • Learn the new syntax of ECMAScript 6
  • Use the new prototype-based features introduced by ES6
  • Execute ES6 in a non-supported ES6 environment
  • Learn how to write asynchronous code using promises - it makes your code more efficient and easier to maintain
  • Find out how to use iterators, iterables, and generators
  • Explore object-oriented programming and create objects using classes
  • Build proxies using the ES6 proxy API and understand its uses
  • Learn how to create JavaScript libraries using ECMAScript 6 modules

Course Prerequisites

In order to be successful in this class, incoming attendees are required to have at least some basic experience working with HTML and CSS. Some exposure to JavaScript would be helpful as well.

Take Before: Attendees should have experience with the topics in the following courses, or should have recently attended these as a pre-requisite:

  • TT4605: Web Essentials: HTML5 / CSS3
  • TT4110:  Introduction to Modern JavaScript

Take After: Our core training courses provide students with a solid foundation for continued learning based on role, goals, or their areas of specialty.  Our web developer learning paths offer a wide variety of continued learning paths such as:
