javascript - 如何在 javascript 中将带有 JSON 对象的二维数组转换为单个数组？

Question

这里我在数组中有一个 JSON 对象，并将其推送到employeeArray，即

employeeArray =[  
  [  
    {  
      "ID":"967",
      "NAME":"Dang, Lance D",
      "Email":"Lance.Dang@xyz.com"
    }
  ],
  [  
    {  
      "ID":"450",
      "NAME":"Starnes, Mitch",
      "Email":"Mitchell.Starnes@xyz.com"
    }
  ],
  [  
    {  
      "ID":"499",
      "NAME":"Cosby, Lance H",
      "Email":"Lance.Cosby@xyz.com"
    }
  ]
]; 

我如何将其放入具有这样的 JSON 对象的单个数组中

employeeArray =[  
  {  
    "ID":"967",
    "NAME":"Dang, Lance D",
    "Email":"Lance.Dang@xyz.com"
  },
  {  
    "ID":"450",
    "NAME":"Starnes, Mitch",
    "Email":"Mitchell.Starnes@xyz.com"
  },
  {  
    "ID":"499",
    "NAME":"Cosby, Lance H",
    "Email":"Lance.Cosby@xyz.com"
  }
];

帮助我如何使用上述二维数组值并在纯 JavaScript 中构建我期望的数组

您想要展平数组，可以使用 reduce 来完成调用:

employeeArray.reduce((p, c) => p.concat(c), [])

ES5:

employeeArray.reduce(function (p, c) {
  return p.concat(c);
}, []);
