如何按键过滤数组?

Question

我需要由庄家筛选数组。键=== 'bovada'。我需要这方面的数据。这个问题对我研究数组很重要。

我期望得到没有foxbet信息的数组。我只能过滤简单数组。我已经两天不能过滤这个数组了…

I tried array。过滤器(i =比;i.bookmakers。过滤器(k =比;K.key == "bovada"))但是，没有

Answer 1

const result = array.filter((arr) => {
let newBookmaker = arr.bookmakers.filter(
(bookmaker) => bookmaker.key == "bovada"
);
if (newBookmaker.length > 0) {
arr.bookmakers = newBookmaker;
return arr;
}
});
