Section 1: Setting Up Your Environment

Before you can even begin to write any JavaScript, you are going to need a couple of things – a text editor and a decent web browser that contains tools for web development. For this, we are going to use the Chrome browser and look at a text editor called Brackets.
Chrome:
One of the most important things about learning JavaScript is learning the console and that includes how to set it up. Chrome has its own built-in console and this is perfect for inputting your scripts and code – even better, it’s free. This is how you get it:
1. Open the web browser you are using and type in
www.google.com/Chrome
2. Download the Chrome browser. From here, it is your choice as to whether you keep Chrome as your primary browser or you just use it for doing your JavaScript. Follow all the on-screen instructions to download and install Chrome browser
3. Open the Chrome browser and look for an Options circle in the top right corner – click it and you will see some more options
4. Select More Tools and then Developer Tools
5. Now select Console and the console pad will load. You should see the symbol > on it – this is your command prompt and it is where all your code will be input.
Now you can begin to use the console in Chrome so take the time out to explore it; learn what it is all about and how to use it.
Shortcut:
There is a shortcut to open your console:
● Download and install Chrome
● In the address bar, type about: blank and a blank page will load.
Getting Started:
Now that you have set up your console, you can type console.log() at your command prompt – this will log you in. Now is the time to begin exploring and learn what JavaScript is all about – as I mentioned earlier, you will find lots of practical examples to help you out through the book so use them and learn. A couple of helpful hints – you can click the button that says Preserve Log to preserve anything that you input and if you want to save your work, right-click anywhere in the console and choose Save As.
Now let’s look at text editors. You can choose any that you want but I would recommend Brackets
Brackets:
Brackets is open source and is specifically designed for web development. It is built using JavaScript making it the very best editor, providing plenty of useful tools and help for you to learn how to code much easier and much more effectively.
1. Open your web browser and type in http://brackets.io/
2. Download the version that corresponds to your operating system – Linux, Windows or Mac
When you open Brackets for the first time, you will be presented with a project named “Getting Started.” Onscreen instructions will show you how to use the features in Brackets
● Opening a folder is simple – click File>Open Folder. You will see this in the file tree that is to the left of your screen. This is your projects folder and it has some settings related to it. To move between projects, simply click on the root folder name in the tree or you can drag the relevant folder form your operating system into Brackets and it will open.
● Instead of showing your opened files in tabs, Brackets shows them in a list titles “Working Files” and you will find this above the tree. Clicking on a file in that tree will allow you to view the file but it won’t get put into the Working Files List. This way, you can look through the files without having to open each one. Any changes that are made to a file will be put automatically into the Working Files list and to add a file to the list without having to edit it first, you simply double-click the name.
To begin with, a single editor will be on show in Brackets view but you can split it so you see two editors. These can be horizontal or vertical and to choose, click View and then on Horizontal Split or Vertical Split. The main view will now show as two and you can view two files at the same time. You will also get another Working Files list so you can see what is open in each pane. You can also drag files between the two panes.
Brackets is very clever in that, whatever view layout you had for each project, it will remember it. Opening a project will show you which layout was there when you saved and closed the project. To close split view and go back to a single pane, just click on View and then on No Split. You won’t shut down any open files by doing this; the separate lists of Working Files will now be merged into one and all changes will be stored until you chose to discard or to save them.
Have a play, learn your way around Brackets and then open a new console, ready to start coding.

Introduction
First, let me congratulate you for taking the time to read my guide to JavaScript. My intention is to guide you through the inner workings of JavaScript. I want you to learn exactly what JavaScript is, how it all works and how all the pieces fit together as well as going into some detail about some of the HTML elements that go together with JavaScript.
JavaScript is an incredibly light language and is easy to learn as well as being dynamic. Brendan Eich designed it in 1995 when he worked for Netscape, the owner of the very first web browser. JavaScript is a web-based programming language that is used for the creation of websites and web pages using other components like Java applets, images and plugins.
JavaScript is an open source language and cross-platform and you will find that all the major websites use it as their core programming language.
To help you through, I have included lots of examples for you try yourself – this is the best way to learn something and I hope that it helps you too. There are also several exercises dotted throughout the book, just examples that you can have a go at. These are designed to compound what you have learned in a specific section and I haven't provided any answers for these. They are merely a way for you to practice and I would urge that you go over them over and again until you are confident. These are not just designed to test your knowledge of the subject but also to test whether you have learned the correct way to write the code. And, at the very end of the book, you will find a mock JavaScript test for you to try, complete with answers.
If you are ready to start learning JavaScript, let’s go.
