Testimonials

Since the first release of RunJS in late 2018, many people from around the world and all kinds of backgrounds have said very kinds words about it.

If you want to know what a piece of JS code will do, there's no substitute for just RUNning it and seeing the result! RunJS has become an essential tool in my daily JS development, writing, and teaching work, unseating a bunch of other tools like consoles, CLIs, and in-browser code editors.

Awesome JS playground here. Its similar to Swift playgrounds - every line of JS code will be evaluated separately, with output printed on the right. Great tool for exploring JS!

RunJS - a desktop app that serves as a JavaScript scratchpad. This is one of my favorite tools for debugging and testing things quickly.

If you want to quickly see what a wee JavaScript snippet evaluates to, RunJS is a delightful way to find out. It's free. And pretty. And cross-platform. I dig it.

So grateful to have discovered RunJS. It's so much easier to practice JavaScript when you can see the solution in real time!

If you've never tried out RunJS before, give it a go! It's a JavaScript scratchpad which can also run your code. The best feature? It supports npm modules!

A good tip for those who are studying JavaScript like me: RunJS! It's a playground that auto-evaluate your code as you type and you can also import libs and stuff
