ES6 i About the Tutorial European Computer Manufacturers Association (ECMAScript) or (ES) is a standard for scripting languages like JavaScript, ActionScript and JScript. It was implementation of ECMAScript. This tutorial adopts a simple and practical approach through JavaScript to describe the new features in ECMAScript 2015 (ES6), ECMAScript 2016 (ES7), ECMAScript 2017(ES8) and and ECMAScript 2018 (ES9). Audience This tutorial is designed for the stemplate oftware programmers who have already worked with JavaScript and wishes to gain in-depth knowledge about the ECMAScript

JavaScript runtime tells us that it thinks something is nonsensical. Those cases come up because the ECMAScript specification has explicit instructions on how the language should behave when it runs into something later, but let's now focus on that first point. Type annotations aren't part of JavaScript (or ECMAScript to be pedantic), so there really aren't any browsers or other runtimes that can just run TypeScript from a version of ECMAScript called ECMAScript 2015 (a.k.a. ECMAScript 6, ES2015, ES6, etc. - don't ask). TypeScript has the ability to rewrite code from newer versions of ECMAScript to older ones such

Node.js the new ECMAScript standards can be used without problems, as you don't have to wait for all your users to update their browsers - you are in charge of deciding which ECMAScript version to use this Arrow Functions Loops Loops and Scope Arrays Template Literals Semicolons Strict Mode ECMAScript 6, 2016, 2017 With those concepts in mind, you are well on your road to become a proficient JavaScript and users a bit slow to upgrade, sometimes on the web, you are stuck to use older JavaScript / ECMAScript releases. 20 You can use Babel to transform your code to be ES5-compatible before shipping it

pure JavaScript, you will need to know the language prior to learning the framework. We will use EcmaScript2016 syntax. You will also need to have previous experience working with HTML.

JavaScript of tomorrow. By using modern tooling we've been able to write Aurelia from the ground up in ECMAScript 2016. This means we have native modules, classes, decorators and more at our disposal...and you

TWO VARIANTS: ASYNC AND SYNC ECMASCRIPT MODULES? • (NEW) SOURCE TYPE “MODULE” NEXT TO “SCRIPT” • ALLOWS NEW SYNTAX: • IMPORT • EXPORT • ALWAYS STRICT • ESM = ECMASCRIPT MODULE EXPORTS, IMPORTS AND FOR EMITTING MULTIPLE ASSETS PER CHUNK + RUNTIME CODE CHALLENGE 1: ESM SPEC VS WEBASSEMBLY API ECMASCRIPT MODULE • LIFE-CYCLE • 1. LOAD • 2. PARSE • 3. BIND EXPORTS AND IMPORTS • 4. EVALUATE (SINGLE

REALLY DIFFICULT TO STATICALLY ANALYZE THESE DAYS • IT GOT BETTER… • AND EVENTUALLY FIXED WITH ECMASCRIPT MODULES VERSION 1 • DEC 2013: FIRST BETA VERSION OF WEBPACK 1 • FEB 2014: 1.0.0 RELEASED JUL FAMOUS! MAR 2015: HARMONY • FIRST PROTOTYPE OF HARMONY MODULES SUPPORT • HARMONY MODULES = NOW ECMASCRIPT MODULES (ESM) • webpack-2 BRANCH 2015 • ADDED SUPPORT FOR NON-JS CONFIGS • PRS BY @monder AND PRETTY BAD AT WRITING DOCUMENTATION (PROVE → SEE WEBPACK 1 DOCS) NOV 2015: FIRST WEBPACK 2 BETA • ECMASCRIPT MODULES ARE NOW NATIVELY SUPPORTED • TREE SHAKING (UNUSED EXPORTS ELIMINATION) • INTERNAL CODE
