Class is an object of key/value pairs containing either properties or methods (functions). Class is effortlessly mixed and extended with other Class instantiations allowing for the most excellent focus of MooTools: Code reuse achieved through maximizing the power of JavaScript's prototypical inheritance but in a Class object syntax more ...
CSS-in-JS is a styling technique by which JavaScript is used to style components. When this JavaScript is parsed, CSS is generated (usually as a <style> element) and attached into the DOM. It enables the abstraction of CSS to the component level itself, using JavaScript to describe styles in a declarative and maintainable way.
In JavaScript, object creation is prototype-based instead: an object creating function can have a prototype property, and any object assigned to that property will be used as a prototype for the objects created with that function. The Prototype framework is not to be confused with this language feature.
JavaScript (/ ˈ dʒ ɑː v ə s k r ɪ p t /), often abbreviated as JS, is a programming language and core technology of the Web, alongside HTML and CSS. Ninety-nine percent of websites use JavaScript on the client side for webpage behavior. [10] Web browsers have a dedicated JavaScript engine that executes the client code.
The Document Object Model (DOM) is a cross-platform and language-independent interface that treats an HTML or XML document as a tree structure wherein each node is an object representing a part of the document. The DOM represents a document with a logical tree. Each branch of the tree ends in a node, and each node contains objects.
In the JSONP usage pattern, the URL request pointed to by the src attribute in the <script> element returns JSON data, with JavaScript code (usually a function call) wrapped around it. This "wrapped payload" is then interpreted by the browser. In this way, a function that is already defined in the JavaScript environment can manipulate the JSON ...
JavaScript-based web application frameworks, such as React and Vue, provide extensive capabilities but come with associated trade-offs. These frameworks often extend or enhance features available through native web technologies, such as routing, component-based development, and state management.
