Does the work get AutoSaved! I am new!
On FreeCodeCamp the code you write in the editor is saved to your browser cache, so don’t rely on the website to save the code. Also, remember to submit the code after you pass the tests or it will not be marked as done
You can play with the code in places like codepen, repl.it or jsfiddle, where I think the code is auto saved while you are working on it (but it may be a thing you have to turn on)
