Old Browser Judgment Judgment for Safari13 and Safari14 and above

Pub.date：2022-02-28
I want to judge old browsers up to Safari 13.
The version of Safari will remain old unless you update your iOS/iPad OS.
Therefore, it often happens that only Safari does not work.
Separating Safari 13 / 14
<script>
console.log('replaceChildren' in window.document);
</script>
Separating Safari 12 / 13
<script>
console.log('visualViewport' in window);
</script>
