An introduction to JavaScript, how it was born, what is it good for, different types and versions of this scripting language, and the compatibility between it and the browsers.

The following sample of code gives an idea of how to add a blinking flash message at the status bar. Adding flash text at the status is very simple for that we use a single if-else loop in function blinkflash(). This script is compatible with IE. Click here to see live example. First of all we define three variables var message for �display message at status bar�, var speed for �set time interval to flash text�, and var control to control blinking of message

In this tutorial you will learn alot of about Radio buttons. Here you will learn how to use radio buttons & for what does they are used.

The basics of using Javascript functions to execute code or perform commands within your pages.

The issue with all of this is that the CouchDB callback is asynchronous, and "this.bar" is now within the scope of the callback function, not the class. Does anyone have any ideas for accomplishing what I want to? I would prefer not to have a handler object that has to make the db calls for the objects, but right now I am really stumped with the issue of it being asynchronous.

JavaScript Operators have a predefined order of precedence which are used to process and evaluate a JavaScript expression. JavaScript Operator Precedence is similar to the Mathematical Operator Precedence and Associativity. Like basic algebra Operator Precedence, JavaScript multiplication and division Operator have higher precedence over addition and subtraction Operator.

JavaScript Expression is a combination of values, variables, operators, and functions that are interpreted (evaluated) as per the program logic define(develop) by JavaScript programmer. JavaScript supports a variety of operators like arithmetic, logical and comparison etc. An operator is a function which acts on any number of operands (inputs) to produce a pre-define operation.

JavaScript Reserved KeyWords are part of the JavaScript language syntax. JavaScript Reserved KeyWords has special meanings and used to instruct JavaScript interpreter to perform a specific pre define task. JavaScript has some reserved keywords which can not be used as an identifier. Using JavaScript Reserved KeyWords as an identifier for variable names, function names, and loop labels results in error.

JavaScript Variables are the main building blocks of JavaScript Scripting language. JavaScript Variables are used for storing (contains) the data (value) and manipulate that data in your programs. Every JavaScript variable has a name, called its ‘identifier’ and optional data called ‘Literals’. JavaScript Variables are declared using JavaScript ‘var’ keyword. JavaScript var keyword allocates storage space for variable to store data. Multiple variables can be declared with one JavaScript ‘var’ keyword. The main advantage of JavaScript variable is, it can hold a value of any data type. Using an undeclared variable causes an error. The best practice of defining JavaScript Variables is with assigned initial values.

JavaScript Literals are the notation for representing a fixed data value that appears directly in a JavaScript program. JavaScript Literals helps us to assign values (initialize) to various JavaScript Data Types and Variables; such as integers, floating-point numbers, strings, and Booleans; enumerated Data Types and compound values such as arrays, records, and objects.

JavaScript Comments allows us to add remarks and a well written explanation about the working of JavaScript code. JavaScript Comments make the code more readable, understandable for future reference. Commenting your JavaScript code makes it easier for others to understand. To increase re-usability of a JavaScript code be, sure to include comments in your scripts. Commenting your JavaScript code is the best practice of JavaScript programming and suits to your aspect of good programming style.

A JavaScript statement is a command to a web browser to perform specific task define (program written) by the user. JavaScript Statements are written with the set of elementary rules that specifies how to write JavaScript programs. A JavaScript program is a set of one or more statements. A statement will have internal components like Variables, Literals, Identifier, reserved keywords, Comments, conditional statement, Arrays, Functions, Objects, Classes etc JavaScript is case sensitive, in the most of cases JavaScript Statements terminated with a semicolon(;) or with Returns(Enter or line-break). Even though semicolon is optional, JavaScript Statements terminated with a semicolon(;) is the best practice of JavaScript programming

JavaScript is mostly used as a client-side scripting language. With Client-side JavaScript, we are able to interpreter with the Document Object Model (DOM) of a web browser. On Client-Side, JavaScript add interactive features to your page. JavaScript allowing us to do plenty of tasks on Client-Side like mathematical calculations, form validation, drop down and sliding menus, message tickers, work with events, work with cookies, add special effects and animation, develop interactive games, customize graphics selections, and create security passwords and many more.
