获取JSON到数组的特定输出[closed]

我在这里得到了一些帮助,这给了我以下代码:

const result = data.report.data.reduce((r, e) => {
  e.breakdown.forEach(el => {
    let key = "data";
    if(!r[key]) r[key] = []
    r[key].push(...el.counts)
  })
  return r;
}, {})

这给了我这个输出:

Object
data: (3) ["558045", "552531", "522877"]
__proto__: Object

但是,问题是我的绘图软件期望如下:

["558045", "552531", "522877"]

我如何调整我上面的代码,以实际只给我上面的输出呢?我试着简单地去掉这条线:

let key = "data";

(index):73 Uncaught ReferenceError: key is not defined
    at e.breakdown.forEach.el ((index):73)
    at Array.forEach (<anonymous>)
    at data.report.data.reduce ((index):72)
    at Array.reduce (<anonymous>)
    at window.onload ((index):71)
