These are some of my favorite online sandbox for Angular and React.
What are online sandboxes?
They are online editors that lets you share your code, test your concepts, do tests in clean environment quickly.
You can spin up new, clean environments without having to do it on your local machine, which usually takes much longer and overtime, they start to clutter.
It can also be helpful for beginners to start coding right away too without to setup all the bundling process.
I use them primarily for testing bugs in a clean environment, as well as replicating bugs so I can share the code along with my issues in Github or Stackoverflow.
