ECMAScript fundamentals

• Presentation slides.
• Tutorial

Overview

This talk aims to give an overview of the new syntax, operators, and primitives in ECMAScript. We present some of the new syntax, such as const, let, and fat arrow (=>), as well as new ways that simplify looping over collections. I also cover new object primitives (sets and maps), as well as promises: what they are and how you can use them to write cleaner, more comprehensible and maintainable async code.

Topics

• New syntax and operators.
• Default arguments.
• Language primitives including sets, maps, and iterators.

Target Audience

This is a beginner level tutrial for Web/Node developers. However, it assumes you know a bit about ECMAScript/JavaScript already.
