JavaScript Introduction
JavaScript is THE programming language for the web, and it’s becoming more and more important in other areas as well. In this module we’ll take a first look at the language and how to make our lives easier by using it efficiently.
- Why is JavaScript Important?
- What is ECMAScript?
- Performance
- Picking the right Libraries
- Developer Tools
JavaScript Language Fundamentals
In this module, we’ll talk about the very basics of JavaScript. JavaScript can be a very tricky language, so we’ll try to explain a couple of its quirks as well. This way, we can avoid surprises later.
- Using Variables
- Primitives and Objects
- Functions: more powerful than you’d expect
- Understanding Scope
- Strict Mode
- Error Handling
- LAB – JavaScript Language Fundamentals
JavaScript Collections
Collections are a big part of OO programming, they allow you to map one-to-many or many-to-many relationships, as well as let you work with sets of data. In this module, we’ll take a look at the different types of collections in JavaScript, and their uses.
- Storing multiple values in Arrays
- Useful Functions and Operators
- Using Objects as Maps
- Sets, Maps and Others
- LAB – Javascript Collections
JavaScript Constructors and Classes
Since ECMAScript 2015 we have native classes in JavaScript. But behind the scene, classes are just syntactic sugar on top of Constructors and Prototypes. We’ll take a close-up in this module.
- Creating your own Objects using Constructors
- Prototypes
- Class syntax
- Using Properties to encapsulate your fields
- The ‘this’ keyword explained
- LAB – Constructors and Classes
Dealing with Async Code in JavaScript
Asynchronous code is really handy in JavaScript, since it allows us to keep the UI responsive while running a lot of code. In this module we’ll see how to make our code run asynchronously.
- Threading in JavaScript
- Using Callbacks
- Event Handling
- Working with Promises
- Async and Await
- LAB – Dealing with Async Code
Structuring JavaScript Applications and Tooling
Hey new JavaScript developer! You are using WebPack right? WebPack? Yes, and Gulp and npm, you need those. Oow and definitely use Babel. It’s soo good… If your face looks like a big question mark right now, that’s quite normal. Setting up a JavaScript project can be quite the challenge. It’s easy to get lost in the overwhelming amount of tools and best practices. In this module we’ll create some clarity about these tools and teach you how to set up a modern JavaScript project.
- Using Libraries
- Content Delivery Networks
- Getting Libraries with npm
- Modules versus the Global Object
- Using Task Runners like Gulp
- Bundling and Minification Tools like WebPack
- PolyFills and Transpilers like Babel and TypeScript
- Tools for Code Quality
- LAB – Structuring an Application
REST Services
This module is about communicating with the backend. REST allows client-server communication using HTTP.
- REST
- Verbs and URLs
- XML and JSON format
- Example with node.js and Express
- LAB – REST Services
Client-side Service Consumption with Vue.js
By using AJAX we can call server-side actions from our client-side code and process the results in a quick, user-friendly manner. In this chapter you will also get an introduction to a popular data binding framework: Vue.js. We will see how we can talk to a REST API from this framework.
- Getting data using AJAX
- Fetch API
- External Libraries
- Vue.js Essentials
- Loading Data in a Vue Application
- LAB – Consuming REST Services
