What is the JS code for view based blocking?

[SakiSakiSakiSakiSaki]

I don't know anything about JS, and I'd rather not destroy my YouTube client with wrong syntax.

What I have so far is

(video, objectType) => {
  // Add custom conditions below
  if (video.viewCount <= 1000 ) {
  return true;
  }
  // Custom conditions did not match, do not block
  return false;
}

Not sure if this will work or not, would like second opinions. Thanks.

I tested this code, and it works fine. There isn't any significant risk in playing around with custom functions because incorrect syntax just results in an error appearing in the browser console and other issues can be easily reverted.
