javascript中resolve、reject是关键字吗？

Question

const promise = new Promise((resolve, reject) => {
  if(allWentWell) {
    resolve('All things went well!');
  } else {
    reject('Something went wrong');
  }
});

我可以更改resolve为res吗？或者resolve在这里有特殊含义吗？

Answer 1

不，它们不是关键字，您可以将它们命名为任何您想要的名称，但在我看来，您应该使名称尽可能具有描述性。

const promise = new Promise((res, rej) => {
  if(true) {
    res('All things went well!');
  } else {
    rej('Something went wrong');
  }
});

promise.then(val=> console.log(val))
