States

All the fiddles in this page (except the last one) run on the same kernel.

The following runs in a stateless environment.

The following two fiddles run on the same state. Check what happens when you run them after the previous fiddle.

The following fiddle runs on a different state.

The states used can only be restored by reloading the page.

Note that a state lives in a kernel and cannot be shared between different kernels (because of potential concurrency issues). For example, state $\mathrm{S}_1$ in kernel $\mathcal{K}_1$ and different from state $\mathrm{S}_1$ in kernel $\mathcal{K}_2$.

Finally, fiddles sharing a kernel but not the state will still share changes to module variables and the filesystem anyway. If that is not desired, you can use a different kernel in stateless mode, which still shares module variables and the filesystem between executions.

For a totally isolated and stateless experience you can restart the kernel on each run as follows. This, however, is much less efficient.
