What is a Javascript?

Answer 1

JavaScript is a scripting computer language originally developed for client-side web development. It is usually used to control browser behavior- open a menu, show a popup, or get more information back from the server. The language is dynamic (you can declare classes and functions on the fly) and flexible (weakly typed). ECMA script standard was developed based on Javascript, and its dialects are now being used for various things, from Gecko layout engine (used by Firefox and other browsers) to Adobe Flex.

Answer 2

JavaScript is a scripting language most commonly used in webpages to provide behaviour. For example, on this webpage, the Ask/Answer tabs are managed by JavaScript. When you click on "Answer", it changes to that tab, without the page reloading. JavaScript has the power to modify a webpage.

JavaScript is a mostly-standardized scripting language, so its uses are not limited to providing browser interactivity. It can be used for anything scripting is viable for.

Web servers can be programmed in JavaScript, for example.

Answer 3

Javascript (unrelated to the Java programming language) is used primarily used in HTML to provide dynamic functionality by manipulating the Document Object Model (DOM) or making additional HTTP requests, also known as Asynchronous Javscript and XML (AJAX) even if XML is not used.

Answer 4

Javascript code is code that can be executed by (any normal) internet browsers. Javascript makes advanced interaction with webpages possible. For example, when filling out some sort of form on the web, Javascript can check (live) if the data you provided was correct and if not, mark some fields with a colour. More advanced Javascript scripts can even get and post data to a server. This allows webdevelopers to create "cool" features on websites. Although things like a Chatbox and a live-updating blog may seem useless to some people, Javascript gives you a few advantages. It can, if used correctly, decrease the amount of data you have to download from a server, and increasing the speed of loading a page. Also, JS is not a new language, but these days, you'll see it more often.

Answer 5

Javascript is a coding language that tells the computer to do things out of the usual HTML-e.g. pop-up windows.

Answer 6

JScript is just a shortening for JavaScript

Answer 7

JavaScript is a code used for interactivity on a site such as this, a code to draw shapes.

e.g. Circle = ellipse(x, y, width, height)
