Introduction to ECMAScript 6 (ES6)

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:

• TT4193: Introduction to React | React Essentials (3 days)
• TT4190: Getting Started with React (5 days)
• Additional React, Redux, NodeJS / MEANStack, Angular or other next level web development courses
• Web security training
• Please contact us for recommended next steps tailored to your longer-term education, project, role or development objectives.

Course Materials

Each student will receive a Student Guide with course notes, code samples, software tutorials, diagrams and related reference materials and links (as applicable). Our courses also include step by step hands-on lab instructions and and solutions, clearly illustrated for users to complete hands-on work in class, and to revisit to review or refresh skills at any time. Students will also receive related (as applicable) project files, code files, data sets and solutions required for the hands-on work.
