What is JavaScript? Nedir?
JavaScript is a dynamic programming language that runs in web browsers and adds interactivity to web pages.
JavaScript was developed by Brendan Eich for Netscape in just 10 days in 1995, but has since become one of the most widely used programming languages in the world. Originally designed as a simple scripting language for browser-side execution, it expanded to server-side use with the emergence of Node.js. JavaScript is based on the ECMAScript standard and is updated with new features every year. Modern features introduced with ES6 (2015) such as arrow functions, classes, modules, template literals, and destructuring have significantly transformed the language. Promises and async/await provide powerful tools for asynchronous programming. Creating dynamic web pages through DOM manipulation, event handling, and AJAX requests is JavaScript's core use case. The ecosystem includes frontend frameworks like React, Vue, and Angular, and backend frameworks like Express and Nest.js. Today JavaScript is used everywhere from full-stack web development to mobile apps (React Native), desktop applications (Electron), and even IoT devices. The npm package manager hosts millions of packages.
