Now, the current promise will be in rejected state and the control. If any of the promises are rejected, this. Be it a reject() call, or an error thrown in a handler. Separately, if an error is thrown, then the return value is a rejected promise for which.catch(…) is triggered with the error it experiences. If you throw an error inside the promise, the catch() method will catch it, not the try/catch. You want to log the error, but keep the promise chain as. Errors thrown this way are not catchable by the caller and will cause the program to crash unless (a) the readfile function itself. .then also catches errors in the same manner, if given. Any time you are inside of a promise callback, you can use throw. .catch handles errors in promises of all kinds: Some of the useful reasons for catching and rethrowing are as follows:
