Essentials in JavaScript ES6 - A Fun and Clear Introduction

Set up a Webpack 4 project from scratch, create a src/index.js, configure npm scripts for start and build, and bundle code into dist/main.js to run in the browser.

Configure Babel with Webpack to transpile ES6 to ES5, install Babel core, Babel loader, and env preset, set up .babelrc and Webpack rules, and verify the local development server.

Discover how ES6 introduces let, replaces var for mutable variables, and enables block scoping with standalone blocks, including private-like variables demonstrated by a salary example.

Destructuring assignment extracts values from arrays into separate variables, assigning them in order. It can pair with the spread operator to capture the remaining elements.

Master destructuring assignment with objects in es6 by extracting magical and power from a wizard object using shorthand syntax and matching left-hand names to object keys.

Explore arrow functions in ES6, highlighting their anonymous by default nature and how named identifiers can reference them, with examples using set timeout and a blastoff invocation.

Explore the map function in ES6 to create an array by applying a callback to each element, with add-one example on 10, 20, 30 and arrow function demonstrating one-line return.

Learn how to declare an ES6 class with a constructor and parameters, access properties with this, add a greet method using a template string, and create an instance with new.

Explore ES6 in a practical mini React app, focusing on JSX, component rendering with ReactDOM, and setting up the project with npm install and babel preset.
