function factorial(n) { return (n <= 1)? 1 : n * factorial(n-1); }
]]> </script>
<form id="form">
<field name="fact" type="number">
<prompt>Tell me a number and I'll tell you its factorial.</prompt>

In the case of a very large file (implying long download times) or a streaming audio source, stream indicates to the interpreter context to begin processing the content as it arrives and should not wait for full retrieval of the content. If not specified, a value derived from the innermost relevant *fetchint property is used. |
