JavaScript, an all important programming language is the building block of the Web. “HTML5 is great. JQuery is cool. Node.JS is awesome. Base those on the solid, powerful basement of pure JavaScript and you can rock the web!” – Javascript.info.

JavaScript is a dynamic computer programming language.[5] It is most commonly used as part of web browsers, whose implementations allow client-side scripts to interact with the user, control the browser, communicate asynchronously, and alter the document content that is displayed (http://en.wikipedia.org/wiki/JavaScript)-

Here is some JavaScript code to catch your interest.

var fruits = [“Banana”“Orange”“Apple”“Mango”];
document.getElementById(
“demo”).innerHTML = fruits.valueOf();

And here is some more…

cars = [“BMW”,“Volvo”,“Saab”,“Ford”];
var i = 0;
var text = “”;

for (;cars[i];) {
text += cars[i] + 
“<br>”;
i++;
}

 

For your reference an earlier blog post (Starting Web Development: I) is copied here to get you started on JavaScript. It includes a list of where to take courses and some of the editors that can be used for practice (remember, all code should be saved with the necessary extension and viewed in a browser).

  1. W3Schools.com – is as simple as it gets Use it as a reference guide or as a learning tool to start learning HTML / CSS and also the very basics of JavaScript and jQuery. Feel free to browse the site as it is very informative and talks about a lot of topics.
  2. Udemy.com – An exhaustive offering of online courses by well known instructors. There are many free courses as well.  Try Mark Lassoff’s free Introduction to Web Development https://www.udemy.com/introduction-to-web-development/?dtcode=jZa6Xtj1WrIE
  3. Codeschool.com – For $29 per month you can take as many courses as you’d like. Caution: Some of the levels of study can be quite challenging but are very well taught. This is a great place to learn CSS, JavaScript and jQuery. Course format entails video instructional lectures followed by practice lessons. Do it at your own pace. For the JavaScript course, check this link https://www.codeschool.com/paths/javascript
  4. http://javascript.info/ – A comprehensive one stop shop for understanding all things about JavaScript syntax. After you recover from a Code School JavaScript course you can dig deeper into javascript.info.
  5. http://www.codecademy.com/ – learn coding for free (check their website for terms and conditions).
  6. Stackoverflow.com for questions and answers about anything to do with software. Feel free to post a question and people will respond.

 

To practice these languages all you need is a browser and an editor. Here are some editors you can use.

  1. Notepad++ – Check here:  http://notepad-plus-plus.org/
  2. Sublime Text – grab it from here: http://www.sublimetext.com/2

To determine if your Windows version is 32-bit or 64-bit, do the following: for a visual guide, click the link below, otherwise you can refer to the list:

http://www.picohelp.com/958/how-to-check-if-windows-8-is-32-bit-or-64-bit-version.html

  • On the Start screen, click the Desktop tile.
  • Press the Win key (Windows logo key) + i
  • Click on PCInfo
  • View information about your computer
  • Download the version of Sublime Text you need.  Download “windows” version if you have a 32-bit version or “windows 64-bit” if you have a 64-bit system.

Happy coding!
