Description

JavaScript High Performance focuses on making your JavaScript code run more efficiently, raising your app performance. ECMAScript 6 (ES6) is the new step to the ECMAScript language, whose specifications are inherited by JavaScript. ES6 gives a vast makeover to JavaScript by adding new syntaxes and APIs to write complex applications and libraries that are easier to debug and maintain. ES6 aims to keep JavaScript accessible for casual developers, even after adding new advanced features. 

To begin with, you will get familiarized with Babel.js, which will help you use the latest features of ES6 in all browsers. You’ll gain a concrete understanding of ES basics and classes, modules, inheritance, as well as the coding style. You’ll build your skills with recommended code organization patterns in JavaScript, making your code easy to organize.

Moving on, we’ll discuss advanced features such as collection types, template literals, and symbols. Next, you’ll see how to use tools to write asynchronous code much better with promises and asynchronous functions. Lastly, we will deal with some experimental proposals and references. By the end of the course, you will understand how ECMAScript is going to be the new paradigm.

What do you need from a tooling point of view to start using the latest JavaScript functionality? 

Installing Tools
03:34

This video deals with the basic setup of transpiling a file from ES6 to JavaScript the browser understands. 

Basic Transpiling
03:43

When we use these new JavaScript language features, we want to use them in the all the browsers and on all the platforms. How can we check if they are supported on all these platforms? How can we choose the right tools to cover all these platforms? 

Browser Support

ES6 Basics
3 Lectures 11:31

In this course, we want to show how to start an ES6 application and start building our application with basic functionality. 

Preview 04:07

In ECMAScript 6, we can use different types of variables. 

let Versus var Versus const
03:11

With an arrow, we can write cleaner code. It makes our code easier to read. An arrow also makes it possible to use lexical this, that is not possible with a normal function. 

Using an Arrow

Classes and Modules
3 Lectures 12:00

In JavaScript, we all know how to use object-oriented programming with prototypes, but this will give us a lot of boilerplate code. In ECMAScript 6 we can write this much cleaner. 

Preview 03:48

When we want to split our JavaScript code from one file to multiple files, we use JavaScript module loaders, such as AMD and CommonJS. Now in ECMAScript 6, modules are natively in the language. 

Modules
03:43

In a lot of languages, we have the concept inheritance, which shows how we can extend from a base class.

In ECMAScript 6, if we want to have a unique list with no doubles or when we want to have a map, we can make use of the collection types 

Preview 04:50

In the new JavaScript, there is a new and shorter way to assign variables. This video will show the viewer how he can use this technique to write well-organized code. 

Destructuring Assignment
03:01

When you want to form a long string with a lot of variables, you need to work with a lot of plus signs to form your end result. In the new JavaScript specifications, you can use template string. A new type has been introduced in JavaScript, called symbol. 

Template Literals and Symbols

Iterators and Generators
3 Lectures 11:08

When we want to expose a next method and release some data once the end user is asking it, we should use a generator. 

Preview 04:37

When you want to loop over an object that is not a list, array… native type that can be looped on, you'd want to make it iterable. 

Iterators
03:13

With generators, you can create coroutines and execute generator code sequentially and parallel. 

Coroutines

Promises
3 Lectures 11:37

When we need to work with asynchronous code, we write it with callback functions. This makes our code very ugly and not easy to read. 

Preview 04:32

When do you want to execute multiple promises at once? How are you going to do that? 

Parallel Processing
03:20

What can you do when you only need to use promises as a feature in your JavaScript application? Well you can use core.js; it is a polyfill. 

Promises by core.js

ES Experimental
3 Lectures 13:36

What can we do with experimental ECMAScript features, how can we check them, and how can we use them? 

Preview 04:00

In this video, we are going to explain some proposals. When you want to try these proposal features of ECMAScript, you can first test them online. 

Some Experimental Examples
04:27

Promises can give you a lot of code, and with async await functionality, this can become shorter. But async await is still in the proposal phase and not officially part of the specifications.

References and Tooling

JavaScript is a dynamic language. When you pass by a wrong type, you are only going to discover it when you are testing your code. Is there a way to check this at compile/build time? Yes there is; it is called type checking.

Preview 05:18

What are all the features of ES6? This video will give you a brief overview and provide you with some reference websites to check out.
