我有一个对象数组.每个对象都有很多键(超过100个),其中一些键可以有我想删除的特殊字符.

我试着用这种方式做我想做的事:

const result = data.map(datum => {
  const keys = Object.keys(datum)
  const replacedKeys = keys.map(key => {
    const newKey = key.replace(/[.|&;$%@%"<>+]/g, '')
  })
  // ??
})

但我确信这不是正确的方式..

我有一个像这样的对象数组:

const data = [
  {

    "year": 2016,
    "state": " mx l",
    "value": 93.10611646419025
  },
  {
    "continent": "Europe",
    "year": 2016,
    "state": "Q  xe",
    "value": 46.14966763264863
  },
  {
    "continent": "Europe",
    "year": 2017,
    "state": " mx l",
    "value": 29.392192664199012
  },
  {
    "continent": "Europe",
    "year": 2017,
    "state": "Q  xe",
    "value": 14.676226327897535
  },
  {
    "continent": "Europe",
    "year": 2018,
    "state": " mx l",

  {
