RunJS For Mac

There are countless things you can do with JavaScript, but you don’t always have an editor at hand to try out new ideas. Of course, there are plenty of online tools for the job, but that would mean adding another tab to an already overused browser.

RunJS is a very simple app with a singular purpose – to provide you with an accessible way to write and test JavaScript code from your desktop. While Electron-based, and therefore essentially a browser itself, this app is a lot more convenient than a web-based JS editor.

The app’s interface is purposely minimalistic and split into two panels: one for writing code and one for viewing the output. As expected, it comes with features like syntax highlighting and indentation, which make your job a lot easier.

By default, RunJS evaluates your code as soon as you type something, but this feature can be disabled if you prefer to execute it manually; in this case, a Run button is added to the UI.

Visually, there are a lot of things that can be changed, from the UI theme to the font and text size. You can also specify whether line numbering or line wrapping to be used, and how invisible characters should be handled.

When it comes to functionality, you can install NPM packages from other JavaScript projects, change the working directory and toggle other advanced features, such as loop protection and holistic evaluation.

If you’re looking for a quick way to test and improve JS code, RunJS is a great tool for the job. From the minimalistic UI to the many ways in which it can be customized, the app certainly impresses, and it makes it very easy to play around with new ideas.
