How to catch errors in synchronous functions in node.js?

Question

In asynchronous functions, we can simply catch the error in callback. For example :

Async func:

fs.readdir(path, function(err){
    //catch error
)

As synchronous functions don't have callback, how can I catch errors?

Sync func:

fs.readdirSync(path);           //throws some error

One way is to use try catch block:

try{
    fs.readdirSync(path);
}
catch(err){
    //do whatever with error
}

Is there any other way to do that? If yes, then which one is better?

No, that's how you do it. Typically you have all your main logic in the try, and then just handle exceptional conditions (errors) in the catch. (And cleanup in the finally.)
