JavaScript is a high-level interpreted programming language. It’s a core technology alongside HTML and CSS for the World Wide Web (WWW). JavaScript is a great choice to start your coding career. It’s easy to learn and allows for dynamic behavior such as adding content, animations, and handling user input without the need to refresh the page.
Web development: JavaScript has been used to create responsive and interactive websites. It manipulates the Document Object Model (DOM) to make websites responsive and interactive. Frameworks like React, Angular, and Vue.js are widely used for building complex, modern web applications.
Mobile development: JavaScript frameworks like React Native and Ionic are used to develop cross-platform mobile applications. These apps can run on both iOS and Android platforms, allowing for a wider reach with a single codebase.
Game development: JavaScript can be used to develop simple web-based games. Libraries like Phaser and Three.js are famous for creating interactive 2D and 3D games that run directly in the browser without the need for additional plugins.
Internet of Things (IoT): JavaScript is increasingly used in the IoT domain. Platforms like Node-RED allow for integrating and automating IoT devices using JavaScript.
Machine learning and artificial intelligence: With libraries like TensorFlow.js, developers can implement machine learning models in JavaScript, enabling web applications to perform tasks like image recognition, natural language processing, and more.
