Javascript

JavaScript is a high-level, dynamic, and interpreted programming language primarily used to create interactive and responsive user interfaces on web pages. It was developed in the mid-1990s by Brendan Eich while working at Netscape Communications Corporation.

JavaScript is primarily used to create client-side scripts that run in web browsers, but it can also be used on the server-side using technologies such as Node.js. JavaScript creates interactive elements on web pages, such as forms, animations, and games. Using technologies such as AJAX can also create web pages that update in real-time without requiring a page refresh.

JavaScript is a universal language, and it’s used in a wide range of applications, such as web development, mobile app development, desktop apps, and server-side scripting. It can be used to create Single Page Applications (SPAs), Progressive Web Apps (PWAs), and Real-Time Applications (RTAs).

JavaScript is an object-oriented programming language that supports features such as objects, classes, and inheritance. It also has a number of built-in things such as Date, Math, and String, and it also has many libraries and frameworks available, such as jQuery, React, AngularJS, and Vue.js, that make it easier to develop complex applications.

JavaScript is a constantly evolving language, with new versions being released regularly, with new features and improvements, such as new syntax, improved performance, and new APIs.

JavaScript is often combined with HTML and CSS to create dynamic and interactive web pages. Together these three technologies are known as the “front-end stack.”
