分割連想配列

-3

私は以下のような連想配列を持っています。サブカテゴリが5以上のときは、2つ以上の部分に分割する必要がありますか？この配列を分割するにはJavaScriptコードが必要です 1つのカテゴリには5つのサブカテゴリしかなく、カテゴリに5つ以上のサブカテゴリがある場合は、残りのサブカテゴリと同じ名前のカテゴリをもう1つ作成する必要があります。分割連想配列

であるはずです。この配列を動的に分割して1つのカテゴリに5つのサブカテゴリしか持たないようにする必要があります。また、カテゴリに5つ以上のサブカテゴリがある場合、残りのサブカテゴリを持つ要素を1つ追加する必要があります。 –

以上5 subcategoryを持つ単一のcategoryエントリを検討 - あなたが必要な場合は牽引以上の要素にそれらを分割するArray.prototype.reduceとObject.assignを使用することができます。
