问题描述
I have this two arrays of objects:
我有这两个 arrays 对象：

I need to match the value of the key debtor_account of the ARRAY ONE, with the value of the key account_number of the ARRAY TWO.我需要将 ARRAY ONE 的键 debtor_account 的值与 ARRAY TWO 的键 account_number 的值相匹配。 If they match, return a new ARRAY TWO containing only the objects where those two keys matched.如果它们匹配，则返回一个新的 ARRAY TWO，其中仅包含这两个键匹配的对象。 Because I will have to use the label and the currency_name from the ARRAY TWO only when the account_number/debtor_account matches.因为只有当 account_number/debtor_account 匹配时，我才必须使用 ARRAY TWO 中的 label 和 currency_name。 These two arrays are coming from different endpoints and I am not sure how to handle this situation.这两个 arrays 来自不同的端点，我不确定如何处理这种情况。

I would suggest creating a Set of all debtor accounts, mapping each debtor account number from array 1 to this new Set.我建议创建一Set所有债务人帐户，将数组 1 中的每个债务人帐号映射到这个新集合。
We'd then use Array.filter() on array 2 to return only the entries that have account numbers present in the debtor set.然后，我们将在数组 2 上使用Array.filter()以仅返回债务人集中存在帐号的条目。
This approach will be efficient, since we'll only iterate each array once.这种方法会很有效，因为我们只会迭代每个数组一次。

You could do this with less code using Array.find() , but this will be inefficient for large arrays.您可以使用Array.find()使用更少的代码来完成此操作，但这对于大型 arrays 来说效率很低。
