Find a way to detect endless loops

[CompuIves]

When a sandbox has an endless loop it won't stop executing until the tab kills the editor. This means that users can lose their sandbox.

Maybe there is a way to limit execution time of a sandbox, or maybe we should add a 'Run' button when you're editing your own sandbox. Would love to hear some thoughts.

Ah interesting! Just checked loop-protect and they've done a really great job, cool solution. Would be cool if we had something similar but then that it alters the AST, like a babel plugin. This is what I quickly found: https://www.npmjs.com/package/babel-plugin-looptar but I sploke with repl.it also and they built something for babel to solve it.

Just found this https://repl.it/site/blog/infinite-loops, interesting as they are using a babel plugin as well.

This is still a bug in the React TypeScript starter. To freeze your tab, open https://codesandbox.io/s/react-ts and type while (true) {}.
