What is Javascript ?
JavaScript is a high-level, interpreted programming language that is commonly used to add interactivity and other dynamic features to websites. It is a client-side language, which means that the code is executed by the web browser on the user’s device, rather than on the web server.
JavaScript is designed on a simple object-based paradigm. An object is a collection of properties, and a property is an association between a name (or key) and a value. A property’s value can be a function, in which case the property is known as a method.
JavaScript, often abbreviated as JS, is a programming language that is one of the core technologies of the World Wide Web, alongside HTML and CSS. As of 2022, 98% of websites use JavaScript on the client side for webpage behavior, often incorporating third-party libraries.
