React Sandbox is an environment/virtual space where React developers can practice and test their code before moving it to the final project. 

You can also use a sandbox if you don’t want to install a development environment on your local machine. For instance, to have a local development server, you have to download Node.js and then install React.

With a sandbox, you can escape the installation part and run, test, and execute your React code in a virtual environment. 

A React sandbox has a pre-configured development environment with tools such as a code editor, a preview window, and a build system.

You stand to benefit in the following ways when you use a React sandbox;

  • Easy setup; you don’t have to download a JavaScript runtime environment to your local machine.
  • Enhances collaboration and code sharing. 
  • Most sandboxes produce code that is optimized for various screen sizes.
  • React sandboxes have a live preview with a hot reload feature, making it possible to view the changes to the rendered page as you write your code. 

These are some of the best React Sandboxes you can use today;
