RunJS是一款为桌面设计的JavaScript和TypeScript编程环境，它允许用户探索和实验这两种语言，同时在编码时提供即时反馈和可视化结果。

这款软件简化了JavaScript的学习过程，提供了实时反馈和每行代码结果的清晰展示。

RunJS支持Node.js和浏览器API，包括完整的DOM访问，增加了使用的灵活性。

它还内置了Babel和TypeScript支持，让用户能够采用最新的语法进行编程。

RunJS还提供了对NPM包的支持，使得尝试新库和框架变得简单快捷。

它的多标签功能、自动完成功能、代码片段收集、类型检查、悬停信息查看以及环境变量管理等高级功能，极大地提升了编程效率和便利性。

RunJS还提供了多种额外的主题，如Ayu、One Dark、Shades of Purple和SynthWave 84等，为用户带来个性化的编程体验。

Explore and experiment with JavaScript and TypeScript, visualise your ideas and get instant feedback as you type.

Exploring JavaScript has never been easier. Live feedback as you type, with per-line results makes it super clear what your code is doing.

With RunJS you have access to Node.js and Browser APIs, including full DOM access. This gives you a level of versatility that's not possible in a standard REPL or Chrome console.

Babel and TypeScript support enables you to write modern, up-to-date syntax.
