ECMAScript 6 (2015) New Features

  • Duration: 3 Days

Course Information

Overview

The demands on the JavaScript language have increased dramatically over the last few years as developers are tasked with writing more and more complex scripts, using JavaScript, AngularJS, NodeJS and many more.

ECMAScript 6 completed in 2015 and formally dubbed “ECMAScript 2015.” Takes JavaScript programming to new levels many developers have been asking for.

The features vary widely from completely new objects and patterns to syntax changes to new methods on existing objects. The exciting thing about ECMAScript 6 is that all of its changes are geared toward solving problems that developers actually face.

This course takes existing JavaScript developers through the new powerful capabilities of ECMAScript 6.

Prerequisites

Experience of developing JavaScript web pages/applications is required.

  • I thoroughly enjoyed this course but do feel that the duration should be extended in order to allow more time to cover all of the topics. Noel was a fantastic trainer, happy to answer any questions and very good at explaining how to do something, thank you.
