JavaScript Editor — React IDE

JavaScript Editor for Android

A real JavaScript editor on Android. Write modern ES6+ JavaScript and React components, run them instantly, and preview the output — all from your phone.

Free on Google Play

JavaScript is the language of the web, and JavaScript Editor — React IDE brings that world to Android. It's a code editor built specifically for JS and React developers who want to write, test, and iterate without being tied to a laptop.

The editor understands JavaScript deeply — it supports ES6+ syntax including arrow functions, destructuring, async/await, template literals, and modules. React JSX is fully supported, letting you write and preview components the way you would in a desktop IDE.

One of the most practical features is npm-style import support. You can import popular libraries like lodash, moment, or axios using familiar syntax, and the editor resolves them from a bundled registry. This means you can test real-world code patterns, not just toy examples.

The app includes a live preview panel for HTML/CSS/JS output, making it genuinely useful for front-end work. Write a React component, see it render. Adjust the CSS, see the change. The feedback loop is fast enough that you can actually get work done on mobile.
