Javascript 需要根据值对对象中的数据进行分组
我正在应用程序中使用React/Typescript，但需要基本JavaScript的帮助。我试图对来自api调用的数据进行分组（在本例中，我将使用模拟数据），而不修改实际的JSON。我需要根据“deviceType”值对数据进行分组。所以，如果有4个对象，如果两个是ipad，两个是iphone，我需要将它们按顺序分组。现在，模拟数据显示的是iPadAir，然后是iPhone6plus，然后是iPadAir，然后是iPhone6plus。我需要对这些对象进行分组，以便新对象首先包含两个ipadAir对象，然后是iphone 6plus对象。我相信这可以通过使用spread操作符复制旧对象，然后在返回之前修改它来实现。以下是数据对象：Javascript 需要根据值对对象中的数据进行分组,javascript,Javascript,我正在应用程序中使用React/Typescript，但需要基本JavaScript的帮助。我试图对来自api调用的数据进行分组（在本例中，我将使用模拟数据），而不修改实际的JSON。我需要根据“deviceType”值对数据进行分组。所以，如果有4个对象，如果两个是ipad，两个是iphone，我需要将它们按顺序分组。现在，模拟数据显示的是iPadAir，然后是iPhone6plus，然后是iPadAir，然后是iPhone6plus。我需要对这些对象进行分组，以便新对象首先包含两个ipadA
