I have been writing node.js client code for a couple of years now, and have
authored a couple open source libraries, but somehow I missed the memo
telling me that I'm supposed to wrap 'synchrounous' callbacks in
process.nextTick(). I kind-of understand why that is a best-practice, but
what I don't understand is what the drawback is if you don't do it.
For example, I write code like this all the time, and have never had a
single problem with it:
function getSomething(args, cb) {
if (!args) { return cb(new Error('args required')); }
if (!args.id) { return cb(new Error('args.id required')); }
SomeDatabase.get({id: args.id}, cb);
}
What are the potential issues with not wrapping those arg checks in
process.nextTick()?
Thanks,
Bryan
