javascript - JSON オブジェクト内のデータを参照する方法

Question

JavaScript を使用して API (正確には VexDB) から情報を要求しました。情報は次の形式です。

[
    {
        "sku": "RE-VRC-17-4815",
        "key": "RE-VRC-17-4815",
        "program": "VRC",
        "name": "MCC VRC Skills Challenge",
        "loc_venue": "Manchester Community College",
        "loc_address1": "1066 Front Street",
        "loc_address2": "",
        "loc_city": "Manchester",
        "loc_region": "New Hampshire",
        "loc_postcode": "03102",
        "loc_country": "United States",
        "season": "In The Zone",
        "start": "2018-03-10T00:00:00+00:00",
        "end": "2018-03-10T23:59:59+00:00",
        "divisions": [
            "Division 1"
        ]
    },
    {
        "sku": "RE-VRC-17-4269",
        "key": "RE-VRC-17-4269",
        "program": "VRC",
        "name": "NH/VT 2018 VRC State Championship",
        "loc_venue": "Manchester Community College",
        "loc_address1": "1066 Front Street",
        "loc_address2": "",
        "loc_city": "Manchester",
        "loc_region": "New Hampshire",
        "loc_postcode": "03102",
        "loc_country": "United States",
        "season": "In The Zone",
        "start": "2018-02-17T00:00:00+00:00",
        "end": "2018-02-17T23:59:59+00:00",
        "divisions": [
            "Division 1"
        ]
    },
    {
        "sku": "RE-VRC-17-4051",
        "key": "RE-VRC-17-4051",
        "program": "VRC",
        "name": "RI Middle and High School VEX Robotics Competition",
        "loc_venue": "Scituate High School",
        "loc_address1": "94 Trimtown Rd",
        "loc_address2": "",
        "loc_city": "North Scituate",
        "loc_region": "Rhode Island",
        "loc_postcode": "02857",
        "loc_country": "United States",
        "season": "In The Zone",
        "start": "2018-02-10T00:00:00+00:00",
        "end": "2018-02-10T23:59:59+00:00",
        "divisions": [
            "Division 1"
        ]
    },
    ....
]

"sku" や "key" などの個別の項目が複数あるため、それらをどのように参照すればよいですか? （私はJavaScriptの経験がほとんどありません）
