minimal evaluation

Delayed evaluation is used particularly in functional languages. When using delayed evaluation, an expression is not evaluated as soon as it gets bound to a variable, but when the evaluator is forced to produce the expression's value. Some programming languages delay evaluation of expressions by default, and some others provide functions or special syntax to delay evaluation. In Miranda and Haskell, evaluation of function arguments is delayed by default. In many other languages, evaluation can be delayed by explicitly suspending the computation using special syntax (as with Scheme's "delay" and "force") or, ...

Client-side JavaScript (CSJS) is JavaScript that runs on client-side, i.e. the web browser, hence is for client-side scripting. While JavaScript was originally created to run on client-side, this term was coined because the language is no longer limited to just client-side, e.g. server-side JavaScript (SSJS) is also available.

The Internet media type for JavaScript source code is application/x-javascript, but the unregistered text/javascript is more commonly used. To embed JavaScript code in an HTML document, it must be preceded with: <script type="text/javascript"> and followed with: </script> Older browsers typically require JavaScript to begin with: <script language="JavaScript" type="text/javascript"> <!-- ...

There are two primary techniques for handling incompatibilities: browser sniffing and object detection. When there were only two browsers that had scripting capabilities (Netscape and Internet Explorer), browser sniffing was the most popular technique. By testing a number of "client" properties, that returned information on computer platform, browser, and versions, it was possible for a scripter's code to discern exactly which browser the code was being executed in. Later, the techniques for sniffing became more difficul ...

Client-side JavaScript - User interaction. Most interaction with the user is done by using HTML forms which can be accessed through the HTML DOM. However there are also some very simple means of communicating with the user: Alert dialog box Confirm dialog box Prompt dialog box Status bar Console Client-side JavaScript - Events. Element nodes may be the source of various events which can cause an action if a JavaScript event handler is registered. These event handler functions are often defined as ...

For an explanation of the tradition of programming "Hello World", as well as alternatives to the this simplest example, see Hello world program. This is the easiest method for a Hello world program that involves using popular browsers' support for the virtual 'javascript' protocol to execute JavaScript code. Enter the following as an Internet address (usually by pasting into the address box): javascript ...

Note: most incompatibilities are not JavaScript issues but Document Object Model (DOM) specific. The JavaScript implementations of the most popular webbrowsers usually adhere to the ECMAScript standard, such that most incompatibilites are part of the DOM implementation. Some incompatibility issues that exist across JavaScript implementations include the handling of certain primitive values like "undefined", and the availability of methods introduced in later versions of ECMAScript, such as the ...
