What are some common async JavaScript errors?

What are some common async JavaScript errors I should be aware of?

Some common async JavaScript errors include 'Unhandled Promise Rejection', 'TypeError: Cannot read property of undefined', and 'ReferenceError: variable is not defined'. Would you like to know how to fix them?

Yes, how can I handle 'Unhandled Promise Rejection'?

To handle 'Unhandled Promise Rejection', you can use the .catch() method on your promise or add a global handler using process.on('unhandledRejection', ...).

What about the 'TypeError'?

The 'TypeError' usually occurs when you try to access a property of an undefined variable. Make sure to check if the variable is defined before accessing its properties.

Thanks! Can you give me an example of a promise that might cause this error?

Sure! If you have a promise that resolves to an object, but you try to access a property before the promise resolves, you'll get a 'TypeError'. Always ensure the promise is resolved before accessing its data.
