javascript - Rejecting error after opening `.catch` -


are these 2 code blocks same? i'm looking open .catch() , log error still want error "uncaught", can return it? or need wrapped in promise.reject()?

block a:

sosomething()     .then(() => {         return "meow"     })     .catch(() => {         console.log(err)         return err     })

block b:

sosomething()     .then(() => {         return "meow"     })     .catch(() => {         console.log(err)         return promise.reject(err)     })

the 2 patterns not same.

the first handles error , returns resolved promise, reaching first function parameter @ chained .then().

the second example returns rejected promise, reaching second function parameter @ chained .then() or .catch().

i'm looking open .catch() , log error still want error "uncaught", can return it?

the first pattern should meet requirement.
