过滤数据并仅显示所需的数据部分

Question

我在json中有数据，想要在node.js中过滤数据。 json中的数据粘贴在下面我想只显示那些set_account：false的数据。

{"menu": {
    "header": "SVG Viewer",
    "items": [
      {"name":"idea"},
        {"set_account":"false"},
        {"id": "Open"},
        {"id": "OpenNew", "label": "Open New"},
        null,
        {"name":"idea"},
        {"id": "ZoomIn", "label": "Zoom In"},
        {"id": "ZoomOut", "label": "Zoom Out"},
        {"id": "OriginalView", "label": "Original View"},
        null,
        {"name":"airtel"},
        {"set_account":"false"},
        {"id": "Quality"},
        {"id": "Pause"},
        {"id": "Mute"},
        null,
        {"name":"vodafone"},
        {"id": "Find", "label": "Find..."},
        {"id": "FindAgain", "label": "Find Again"},
        {"id": "Copy"},
        {"id": "CopyAgain", "label": "Copy Again"},
        {"id": "CopySVG", "label": "Copy SVG"},
        {"id": "ViewSVG", "label": "View SVG"},
        {"id": "ViewSource", "label": "View Source"},
        {"id": "SaveAs", "label": "Save As"},
        null,
        {"name":"jio"},
        {"id": "Help"},
        {"id": "About", "label": "About Adobe CVG Viewer..."}
    ]
}}

使用array.filter：

var inventory = [{
  name: 'apples',
  quantity: 2
}, {
  name: 'bananas',
  quantity: 0
}, {
  name: 'cherries',
  quantity: 5
}, {
  name: 'cherries',
  quantity: 8
}];

function findCherries(fruit) {
  return fruit.name === 'cherries';
}

console.log(inventory.filter(findCherries));
