Как из массива достать объекты, у которых одно из свойств имеет определённые значения?

Question

const arr = [
  { "Name": "Alex", "sex":"man","age":50,"workplace":"office"},
  {"Name": "Katya", "sex":"woman","age":33,"workplace":"office"},
  {"Name": "Igor", "sex":"man","age":22,"workplace":"park"},
  {"Name": "Olga", "sex":"woman","age":19,"workplace":"park"},
  {"Name": "Maks", "sex":"man","age":40,"workplace":"hotel"}
];

let arr2 = [];

for(let prop in arr){
  if(arr[prop].workplace == "office"){
    arr2.push(arr[prop]);
  }
}

console.log(arr2);

Мне нужно вывести не только обьекты с office, а чтобы еще выводило hotel, как это сделать?

Answer 1

[0xD34F]

const key = 'workplace';
const values = [ 'office', 'hotel' ];

const result = arr.filter(n => values.includes(n[key]));

// или

const result = values.flatMap(function(n) {
  return this[n] ?? [];
}, arr.reduce((acc, n) => ((acc[n[key]] = acc[n[key]] ?? []).push(n), acc), {}));

// или

const filter = (arr, key, values) =>
  arr.filter(function(n) {
    return this.has(n[key]);
  }, new Set(values));


const result = filter(arr, key, values);

var arr = [{ "Name": "Alex", "sex":"man","age":50,"workplace":"office"},
{"Name": "Katya", "sex":"woman","age":33,"workplace":"office"},
{"Name": "Igor", "sex":"man","age":22,"workplace":"park"},
{"Name": "Olga", "sex":"woman","age":19,"workplace":"park"},
{"Name": "Maks", "sex":"man","age":40,"workplace":"hotel"}
var arr2 = [];

for(var prop in arr){
if(arr[prop].workplace == "office" || arr[prop].workplace == "hotel"){
arr2.push(arr[prop]);
}
}
