[removed] What's more efficient, IF block or TRY/CATCH?

Question

I\'d love some other opinions on what\'s more efficient in this code. Basically in the following code, there\'s a setInterval loop and I need 4 requirements to be true befor

Answer 1

Use the if statement. I don't know what the overhead is for a TRY/CATCH, but I suspect it's far greater than evaluating a boolean expression. To hit the TRY/CATCH you will have to: execute a statement, generate an error [with that associated overhead], log the error (presumably), made a stacktrace(presumably), and moved back into the code. Additionally, if you have to debug code near those lines the real error could get obfuscated with what you are TRY/CATCHing.

Furthermore, it's a misuse of TRY/CATCH and can make your code that much harder to read. Suppose you do this for longer or more obfuscated cases? Where might your catch end up?

This is referred to as Exception handling

EDIT: As commented below, you only take the runtime performance hit if you actually cause an exception.
