About JavaScript

JavaScript is one of must popular languages for web development.

It is needed in order to make web pages alive. Today JavaScript can be run not only in the browser, but also on the server.

Why JavaScript Playground/Sandbox/Repl?

Learning, practicing and prototyping is much easier right in the javascript playground, because the browser is designed to run javascript. This is the perfect coding IDE.

In turn, PlayCode tries to use all the browser features to ensure maximum, comfortable run javascript sandbox.

REPL - read-eval-print-loop, simple preconfigured coding environment which quickly shows javascript execution result. Just type your code and repl it. No configs or "npm install".

So, you just open PlayCode without installing anything, write code, javascript playground runs your code instantly and shows the result. Focus on learning javascript and practicing.

React, vue, tailwind css at your fingertips
At first I didnt quite understand the value of this deal, so took it for a spin, and I immediately got hooked :) let me just start by saying this is SOOOO super sleek!! Ran a few bugs intentionally and was shown an immediate and exact description of the bug that I had created. The debug feature is worth the price alone! Then I spun up a react project within seconds, (spun up meaning I clicked a button!) and a live preview was INSTANTLY there! no npm run start or anything. and there is virtually any hot frontend framework you can think of vue.js 3 is there! and a whole range of css frameworks including my personal favorite: tailwind css. super pleased!!!!!!
Great for learning, testing and saving time
I use this for learning and testing various web technologies. Gone is the time spent setting everything up, I also get an instant live preview of my work coupled with a useful console. I work with tailwindcss, alpinejs, bootstrap and I can easily explore other technologies. The author is responsive and maintains the application. I requested some frameworks, these were subsequently added. I am glad to have this tool in my arsenal as it changes the way I now work on the web.

A central place to try out code and test new ideas out
I need a central (online) to try out code and test new ideas out. PlayCode is simple to use, elegant, and seems to have covered all the main frameworks and libraries.
Just what I am looking for
It's just great! Very underrated tool, extremely useful for devs and other dev enthusiasts and everyone who want to learn coding!
Great and recommended
An attractive and useful code editor especially the subdomain feature is awesome. I would recommend people to try Playcode. Nice job, keep going!

Very nice experience
A very nice experience, a beautiful editor that meets all the needs of JavaScript, the ability to add external libraries is great, windows and customize them are one of the best features, also the most important thing is the console and showing the result in a separate window, a really great thing. I highly recommend trying it, it's worth it
