Javascript Try-Catch Performance Vs. Error Checking Code

Question

Would it be faster to just put code inside a try-catch block instead of performing various error checks?

For example..

function getProjectTask(projec         


        

Answer 1

Performance wise try-catch is 20-50% slower than if checks (https://jsperf.com/throw-catch-vs-if-check/1).

So, For rare usage, doesn't make much difference. For heavy usage, it might make some difference.

However, I feel it's bad practice to use try-catch, if it can be done by if checks except if it greatly reduces readability.
