- kinkdr 10y agoIt is in essence: read((err, txt) => { console.log(txt) }) Or read().then((txt) => console.log(txt)) Why is it bad?
- olalonde 10y agoAnd how do you suggest to do that without "blocking"? :) Sure, you could use a stream but that isn't always possible or practical.
- solipsism 10y agoThat's not what blocking means.
- c-smile 10y agoWell, it depends... async function is blocked on await statement, after all that's why it has such a name. It does not block the whole VM but task (async function) is effectively blocked for an observer inside it.
- solipsism 10y agoYes but when you talking about async/await, "blocking" means "blocking the thread". And this is very clearly what mehwoot meant.
