    Non-standard
    This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

    Summary

    console.log(e.lineNumber) // 2

    window.addEventListener('error', function(e) {
      console.log(e.lineno); // 5
