Javascript's performance.now() and Nodejs
<p>I'm new to Nodejs and I'm confused about something when timing:</p>

<p>If Nodejs is Javascript, then why Javascript's performance.now() doesn't work on Nodejs and I'm forced to use console.time() or the like?</p>

<p>How can I know what other Javascript functions doesn't work on Node?</p>

<p>Thanks!</p>
