Course overview

ECMAScript was created to standardize JavaScript which is its main implementation. ECMAScript is the most used language for writing web client scripts and for writing Node.js server applications.

At the end of this course you will know the major functionalities of ECMAScript which will allow you to create modern, robust and modular web or back-end applications.

This course, updated for ECMAScript 2019, covers ECMAScript from version ECMAScript 2015 (ES6) up to ECMAScript 2019.

Learning outcomes

This course teaches participants the following skills:

  • Identify and have a general knowledge of ECMAScript and JavaScript
  • Know the evolution process of ECMAScript
  • Know the contributions of ECMAScript standards since ECMAScript 2015 (ES6)

Prerequisites

To get the most out of this course, participants should have:

  • Basic knowledge of HTML
  • Have taken the course ‘JavaScript: language fundamentals’ or have equivalent knowledge

Target audience

This course is intended for the following participants:

Developers, integrators, software architects, technical project managers

Course Outline

1 Introduction to the ECMAScript standard - A brief history of ECMAScript - JavaScript vs ECMAScript - ECMA International, the TC39 committee and the ECMAScript evolution process - The main features of ECMAScript, from the beginnings to today - Compatibility of web browsers and Node.js with ECMAScript - Transpilation and backward compatibility

Workshops: - Exploring compatibility tools: caniuse, kangax,… - Configuring an ECMAScript development environment and using a transpiler

2 The basics of ECMAScript - Declaration of variables and temporal dead zone - Code blocks - Scopes - Strict mode and ECMAScript

Workshops: - Using ‘let’ and ‘const’ - Case study: scopes

3 Operators and parameters - Exponentiation - Destructuring - Rest - Spread - Functions: parameters default values - Functions: named parameters - Functions: multiple return values

Workshops: - Using the new operators ‘rest’, ‘spread’ and ‘destructuring’ - Using operators with functions

4 Template Literals - String interpolation - Multi-line strings - Tagged template literals and tag functions

Workshops: - Using character string interpolation instead of concatenation - Using a DSL with tagged template literals

5 Arrow Functions - Definition and syntax of arrow functions - Syntactic traps - Lexical variables
