I think I would be good. They are using the ace text editor, so something simple like:
on pageload:
var t = localStorage.getItem("textbackup");
if (t){
__editor.setValue(t);
console.log('restoring from backup');
} else {
__editor.setValue(document.getElementById('basic_intro').innerHTML);
console.log('putting in the intro');
}
and on any action:
var text = __editor.getValue();
localStorage.setItem('textbackup', text);

That's definitely useful, but the current Rust playground already does this (sorry for not being clear in my post). I meant a more full-featured history where you can view multiple previous edits, not just restore the last one.
on pageload: var t = localStorage.getItem("textbackup"); if (t){ __editor.setValue(t); console.log('restoring from backup'); } else { __editor.setValue(document.getElementById('basic_intro').innerHTML); console.log('putting in the intro'); }
and on any action: var text = __editor.getValue(); localStorage.setItem('textbackup', text);
It's the approach I've taken in my version a playground for a different program. http://xqt2.com/mjslab/mjslab.html
