title: Replacement for try/catch in nodejs due to performance overhead
body: <p>I am currently using <a href="https://stackoverflow.com/questions/4467044/proper-way-to-catch-exception-from-javascript-method-json-parse">try/catch to handle JSON.parse errors</a>. But I have just recently found out after reading some <a href="http://innofied.com/node-js-best-practices/" rel="nofollow noreferrer">best practices</a> that using try/catch on nodejs has some <a href="http://jsperf.com/try-catch-performance-overhead" rel="nofollow noreferrer">performance overhead</a>. Is the performance overhead fixed already and is there another way to avoid errors on JSON.parse without using try/catch?</p>
