javascript - 简化 promise

Question

如何简化此语句:

Foo.execSomething(k,v).then(function(){/*do nothing*/},(err) => {
  console.log(err)
}).catch((err) => {
  console.log(err)
});

我经常调用这些后缀(从.then开始)，我不在乎它是否成功，但我关心它何时失败，有没有更简单的方法来做到这一点？

仅仅使用 catch 函数怎么样？

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/catch

The catch() method returns a Promise and deals with rejected cases only. It behaves the same as calling Promise.prototype.then(undefined, onRejected).
