If you are someone who wants to quickly just lookup some code in a GitHub repository or even fork or edit it, then this is a good handy trick to know.
NOTE: If you are not a PRO member of codesandbox then the trick will work only on Public repositories
Steps to follow (if the GIF doesn't sum it up 😜):
STEP 1: Open any Public GitHub repository.
STEP 2: Go to the URL and append 'box' to your github.com URL in-between 'hub' and '.com' and it will redirect to CodeSandbox.
Here's an example:
Change the GitHub URL:
https://github.com/bhatvikrant/react-thumbnail-player
To:
https://githubbox.com/bhatvikrant/react-thumbnail-player
And that's all you have to do!
