function * createStuff(num){
  let ret = [];
  for(let i = 0; i < num; i++){
    ret[i] = i + 1;
  }
  
  for(let i = num - 1; i >= 0; i--){
    let rand = Math.floor(Math.random() * i);
    yield ret[rand];
    [ret[rand], ret[i]] = [ret[i], ret[rand]];
  }
}

var result = createStuff(61);

Sorry, but you've not described an issue here.

It looks like a good problem ，View Console Message

Exiting potential infinite loop at line 3. To disable loop protection: add "// noprotect" to your code

add // noprotect can solve this problem

in runner.js
```js
/**
   * Update the loop protoction hit function to send an event up to the parent
   * window so we can insert it in our error UI
   */
  loopProtect.hit = function (line) {
    console.warn('Exiting potential infinite loop at line ' + line + '. To disable loop protection: add "// noprotect" to your code');
    runner.postMessage('loopProtectHit', line);
  }

So , this may not be a bug
