Run JavaScript in the cloud with Node.js already set up.
Start coding free →JavaScript is the scripting language of the web, running in every major browser. It handles interactive pages, event responses, form validation, and animations. Through Node.js, the same language also runs server-side code for APIs and backend services. It is a high-level, dynamically typed language that supports object-oriented, functional, and event-driven programming styles. A RunCode workspace comes with Node.js, npm, and VS Code ready to use.
Open a JavaScript workspace →JavaScript works alongside HTML and CSS in the browser to add interactivity and dynamic behavior to web pages. Through Node.js, the same language runs server-side code for APIs, CLI tools, and backend services. A broad ecosystem of open-source libraries and frameworks including React, Angular, and Vue.js extends what you can build. Create a new JavaScript workspace on RunCode and you have a working environment from the start.
