に変換したいです構造。私はlodash groupByを使って試してみましたが、上記の構造を達成できませんでした。私ができることのどんな助けもgreatfullになるでしょう。

'payor_name'が異なります。 –

はい.. '' 'payor_name'''は異なることがあります。その場合、もう1つのエントリは同じ構造の' 'payors''配列に入ります。 –

@NinaScholzがqnを編集しました。 –

あなたはlodash経由でこれを行うことができます（一部のキーをスキップし、それらを扱う） -

がこれを最もエレガントに感じました –

プレーンJavaScriptでは、あなたは同じグループ項目に参照としてハッシュテーブルを使用することができますし、プレフィックスがpayorの場合はルックアップでデータを区切り、データをグループ化し、残りのデータを関連データに使用します。

var data = { rate_cards: [{ doctor_id: "xxxxxx", doctor_name: "Dr. Dre", practice_id: "xxxxx", is_owner: 0, policy_id: 1, policy_name: "GOLD Super Gold", payor_id: 1, payor_name: "AMEX", payor_registration_number: "AMEX123", payor_contact_email: "[email protected]", payor_support_number: "PHONE", payor_logo_url: "url", doctors_policies_ratecards_id: 1, ratecard_activation_status: "Pending", ratecard_id: 1, ratecard_validity: "2017-04-17T13:16:58.000Z", ratecard_details: "{'Root Canal': 300, 'Consultation': 500}", onboarded_status: "Available" }, { doctor_id: "xxxxxx", doctor_name: "<NAME>", practice_id: "xxxxxx", is_owner: 0, policy_id: 2, policy_name: "GOLD Super Gold", payor_id: 1, payor_name: "AMEX", payor_registration_number: "AMEX", payor_contact_email: "[email protected]", payor_support_number: "<PHONE>", payor_logo_url: "url", doctors_policies_ratecards_id: 2, ratecard_activation_status: "Pending", ratecard_id: 1, ratecard_validity: "2017-04-17T13:16:58.000Z", ratecard_details: "{'Root Canal': 300, 'Consultation': 500}", onboarded_status: "Available" }] },
