Dynamic HTML (DHTML), for example, loading new page content or submitting data to the server via AJAX without reloading the page.Ījax, short for Asynchronous JavaScript and XML, is is a set of web development techniques that allows a web page to update portions of contents without having to refresh the page. The most common use of JavaScript is to add client-side behavior to HTML pages, a.k.a. It is also being used in server-side programming, game development and the creation of desktop and mobile applications. (Source from Wikipedia) It is most commonly used as part of web browsers, whose implementations allow client-side scripts to interact with the user, control the browser, communicate asynchronously, and alter the document content that is displayed. JavaScript is prototype-based with first-class functions. Alongside HTML and CSS, it is one of the three core technologies of World Wide Web content production: the majority of websites employ it and it is supported by all modern web browsers without plug-ins. It has been standardized in the ECMAScript language specification. JavaScript is a high-level, dynamic,untyped, and interpreted programming language. You don't need special tools to scrape JavaScript pages (other than the tools necessary to execute the JavaScript, or trigger it to execute) just like you don't need special tools to scrape.
