I don’t understand what it means by “the error is thrown asynchronously”, which seems to be the core reason for why try…catch won’t work with asynchronous functions.


In this lesson it said the try…catch syntax don’t work for asynchronous errors. But while I’m reading this lesson, it says that the try…catch syntax can work for both synchronous and asynchronous errors.


I’d like to find out it as well.

I’d like to know the answer to the above question. I’ll post below the corresponding section in the lecture for clarity :
“…We would want the try...catch statement in naiveAsyncErr.js to catch this error, but it cannot since the error is thrown asynchronously.”

In the context of the lesson you are referring to :
Async / await makes your code look synchronous , and in a way it makes it behave more synchronously. Therefore in that case you can use try…catch statement.
