javascript - Why does adding </script> in a comment break the parser? -


this question has answer here:

why adding </script> in comment break parser? bug or there in documentation i've overlooked?

i've tested in chrome, firefox, opera, internet explorer , produce same result.

single-line comment:

function foo(){    // </script>    alert("bar");  };    foo();

multi-line comment:

function foo(){    /*        </script>    */    alert("bar");  };    foo();

this happens because html parser defined w3c totally separated javascript parser. after <script> tag looks closing </script>, regardless it's inside comments or strings, because treats js code normal text.
