Why split the <script> tag when writing it with document.write()?

Browsing through some Chromium source (see line 45ff), I found:

in_script_tag: function(code) {
  return "<script>" + code + "</scr" + "ipt>";
},

Does anyone know why the author chose "</scr" + "ipt>" over "</script>"?

Answer 1

Inside a <script> tag </script> ends it, no matter where it occurs.

Example:

<script>
alert('</script>');
// anything here will not be executed anymore
</script>

The reason for this is simply that the browser does not know anything about JavaScript strings etc. so when it sees </script> it always closes the <script> tag.
