### Java Script

JavaScript, also known as ECMAScript (the untrademarked name used for the standard), is a dynamic programming language. 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. So, what do you need to learn JavaScript, the answer is simple:
1. Basic knowledge of using a personal computer (like creating folders and files, copy, cut, paste, edit).
2. A basic text editor. All personal computers comes with a text editor (like Notepad for Windows, TextEdit in Mac, gedit in Linux with GNOME etc). You can also use other more advanced text editor if you have like Adobe Dream Weaver, or if you prefer the free ones just search online. But a very basic one will do.
3. A browser – All modern PC will come with a browser in build (internet explorer for Windows, Safari for Mac). You can also download a third party browser like Google Chrome or Mozilla Firefox. The browser is like a channel to browse the net, or to see your HTML pages comes to life.
4. Knowledge of HTML – well you’ll need to know HTML and preferably CSS. But don’t worry if you didn’t know HTML or CSS, just browse our tutorial and learn.
JavaScript can be embed in the html document or can be called form a separate file. A basic script that will write "Hello World!" when a button is clicked:
<!DOCTYPE html>
<html>
<title>JavaScript</title>
<script type="text/javascript">
function hello(){
document.getElementById('hello').innerHTML = "Hello World!";
}
</script>
<body>
<h1>My First JavaScript</h1>
<button type="button" onclick="hello();">Click Me.</button>
<p id="hello"></p>
</body>
</html>
Save the above file as an HTML document and open in your browser to see the effect. So, go ahead and learn more JavaScript.

### A Simple Login Class Using PHP and MySQL

Login System is always required for any web application that is dynamic. So, this is what actually happened to me. Every website I created, require some form of login system. So, I usually integrate a login system. The problem is that when I update some security features, I've to re-code for all those website. This unique problem, leads me to the creation of this tutorial inspired by the Hashing Security blog.
The idea here is to separate the login system from the rest of the application. The best way to implement this is to use a Login Class and simply integrate the class to any application you design. In this tutorial, I would like to make the login system as secure as possible, hence I would like to ensure a strong encryption of passwords. Now instead of designing my own encryption technique, I'll use a strong and reliable technique described by Crack Station - a Hashing Security blog. Hence before you start download this PasswordHash.php file from GitHub.

### CSS - Styling your Website

### A Simple Website Counter Script using PHP

Just the other day, I was asked about how to create a website counter script. Mostly the question is for PHP, so, here, instead of directing you to sophisticated scripts - especially for beginners - we'll show you how to do that in a simple and effective way starting from scratch. To solve this problem, you'll need a place to store your data - visitors no - in some place. Then when someone visit your website, just read the value form the old data and increase by 1 then display the value and replace the value in your storage place. First of all, create a file called count.dat. Open your favorite text editor and create a new PHP class for this purpose and a method to handle the data lets call this file counter.php.
class hitCounter { //Set a File Name public $fileName = "count.dat"; public function getHitCount(){ //Read the previous value of counter from file$counter = intval( trim(file_get_contents($this-&gt;fileName)) );$counter++; //Store the ne…
