Prompted by new concepts, such as Ajax since 2004 was a new interest for JS. JavaScript is increasingly used by Business Web Developer for rich client applications that transfer the appearance and operation of conventional desktop applications to Web-based applications. The language plays a key role.
Besides Ajax functionality, most of these libraries have their own base for object-oriented programming, an abstraction layer for comfortable work with DOM, as well as graphical effects such as animations. But even before the widespread use of Ajax, there were collections of functions to support the cross-browser programming.
The well known JavaScript libraries and frameworks include Dojo Toolkit, Ext JS, jQuery, MooTools, Prototype, and Qooxdoo the Yahoo! UI Library. Some JS applications implement their own projects using already existent other languages to expand the expressive possibilities of JS to run scripts written in other languages in the browser, or simply for entertainment or as a demonstration.
Dialogue methods
In most cases, the interaction with the user involves changes in content of the HTML document, especially through forms in the document. It uses JavaScript via the DOM (Document Object Model) to the elements of the HTML document. In addition, three methods of the Window object are prepared: alert (), confirm () and prompt ().
With each of these methods, a Business Web Developer can address the user or ask for input. The user must first close the modal window before he can return to the calling document.
In a finished script, these methods are rarely encountered during the script development, however, they are often used to identify errors in order to examine with little effort a variable value or to determine whether a particular point in the script is ever reached.
In computing, C is an imperative programming language. Invented in the early 1970s to rewrite UNIX, C has become one of the most used languages. Many modern languages like C + +, Java and PHP show aspects of C.
C is referred to as a low-level language in the sense that each instruction of the language is designed to be compiled in a number of machine instructions which are fairly predictable in terms of memory use and computational load.
It offers an array of integers and floats designed to correspond directly to the types supported by the processor. There is also extensive use of the concept of pointer. It has a notion of type compound, but offers no operation that deals directly with objects of the highest level (computer file, string, list). These more advanced types should be treated by manipulating pointers and compound types.
