 ==== What is Javascript ====
   * JavaScript is the most popular scripting language on the internet and works in all major browsers.
-  * It is a lightweight, interpreted language that is embedded into webpages to add interactivity.
-  * JavaScript can read and write HTML page elements, react to events, validate data, create cookies.
-  * JavaScript was invented by Brendan Eich of Netscape but is now known officially as ECMAScript (current version is ECMA-262).
-  * A simple "Hello World" example <code html>
-<script type="text/javascript">
-<!--
-document.write("Hello World!");
-//-->
-</script> </code>
-  * JavaScript code may be located
-    * In the head - executed when called
-    * In the body - executed while loading
-    * In an external file called from either the head or the body e.g. <script src="abc.js"></script>
-==== Basic Syntax ====
-  * JavaScript is case-sensitive.
-  * Statements may omit the final semi-colon but should not.
-  * Blocks may be grouped together using curly braces { }.
-  * JavaScript uses java-style comments: // and /* */.
-  * JavaScript variables are case-sensitive and must begin with a letter or underscore.
-  * Variables are automatically declared when first used but should be explicitly declared using e.g. var a = 5;
-  * JavaScript uses standard C/Java operators e.g. +-*/%, ++, +=, &&, ||, !, + (concatenation).
-  * JavaScript uses C/Java comparators >,>=,==, !=, a?b:c. It also uses === to test equality of value and type.
-==== Basic Structures ====
-  * if {} else if {} else {}
-  * switch (n) { case 1: stmt; break; default: stmt; }
-  * for (var=start;var<=end;var=var+inc) {}
-  * while (condition) {}
-  * do {} while (condition) ;
-  * //break// and //continue// both valid in a loop.
-  *
