// From: https://gist.github.com/billti/a2ee40e60611ec9b37b89c7c00cd39ab
// This script is benign and scrubs the v8 log file from oddities that deoptigate currently can't deal with (because
// it hasn't been updated in a while and is not capable of dealing with unknown content in the log)
// Basically run this on a v8.log and feed the output to deoptigate to have it all work

  // Removes lines containing "extensions::SafeBuiltins:" or "v8/LoadTimes:"
  if (badLines.test(line)) return;
  // Remove the http://localhost:8000/-like prefix.
  const scrubbed_line = line.replace(webPrefix, "");
