JavaScript
JavaScript is the ubiquitous, high-level programming language of the web. It enables interactive, dynamic behavior in browsers and, with Node.js, on the server—making it the backbone of modern full-stack development.
Overview
JavaScript is a versatile, event-driven language that runs in the browser and on servers (via Node.js). It supports multiple programming paradigms — imperative, functional, and object-oriented — and provides APIs for DOM manipulation, asynchronous operations (Promises, async/await), and browser features. Modern JavaScript (ES6+) includes modules, arrow functions, destructuring, classes, and many language features that improve readability and developer productivity.
How I Use JavaScript
I use JavaScript as the core language for building interactive frontends and scripting backend logic. On the frontend it powers UI behavior, fetch logic, form validation, and integrations with third-party libraries. For tooling and build pipelines I rely on Node.js-based tools (Vite, Webpack, npm/Yarn). I write modular, testable code using ES modules, adhere to linting rules (ESLint), and use Jest/Testing Library for unit and integration tests. Async flows are handled with Promises and async/await, and I optimize performance with debouncing, throttling, and code-splitting.
Why JavaScript?
JavaScript is essential because it runs everywhere — in every browser and on servers via Node.js — making it the lingua franca of web development. Its large ecosystem (npm), extensive tooling, and active community mean solutions exist for most problems. JavaScript’s flexibility allows rapid prototyping and production-ready applications alike. Combined with frameworks like React and runtimes like Node.js, it enables full-stack development with a single language, simplifying context switching and accelerating delivery.
