The difference between import; export and export from

my colleagues claim that the three pieces of code are different, and my perception is the same (packaging). But neither of us found the relevant documents.
what are the similarities and differences of the following three codes

  • 1
export { default as AAA } from "./aaa"
export { default as BBB } from "./bbb"
Nov.27,2021

1 and 2 make no difference, they are all named exports, and 3 is the default export class.
from the obligation of argument, if someone thinks that something is different, he must give proof, because there is no way to directly prove without , and any proof can be regarded as but not found . This is called evidence without proof, so your colleagues think that there are differences in these three ways, first of all, you have to point out where the differences are.

thinking, except for the third variable that doesn't get AAA and BBB. I can't think of any difference. Ask your colleague if you want to give it to me. < span class= "emoji emoji-grimacing" >
