JavaScript check if array values exist in array of objects

March 28, 2023

Hi I’ve an array and I’ve an array of objects

const factArr = ['743156', '743157']

[
    {
        "id": null,
        "name": null,
        "adsFactId": "743156"
    },
    {
        "id": null,
        "name": null,
        "adsFactId": "743157",
    },
    {
        "id": null,
        "name": null,
        "adsFactId": "743158",
    },
    {
        "id": null,
        "name": null,
        "adsFactId": "743159",
    },
    {
        "id": null,
        "name": null,
        "adsFactId": "743976",
    },
    {
        "id": null,
        "name": null,
        "adsFactId": "744961",
    },
    {
        "id": null,
        "name": null,
        "adsFactId": "746809"
    },
    {
        "id": null,
        "name": null,
        "adsFactId": "747229"
    },
    {
        "adsId": null,
        "name": null,
        "adsFactId": "747231"
    },
    {
        "id": null,
        "name": null,
        "adsFactId": "749059"
    }
]

I want to check factArr values exists within this object, equal to(adsFactId). If yes I want to add two properties for that object checked:true, checkBoxPatched: true

so the O/P should be

[
    {
        "id": null,
        "name": null,
        "adsFactId": "743156",
        "checked": true,
        "checkBoxPatched": true
    },
    {
        "id": null,
        "name": null,
        "adsFactId": "743157",
        "checked": true,
        "checkBoxPatched": true
    }
    //with the other objects
]

Anyways we can achieve it

>Solution :

const factArr = ['743156', '743157'];
const arr = [
    {
        "id": null,
        "name": null,
        "adsFactId": "743156"
    },
    {
        "id": null,
        "name": null,
        "adsFactId": "743157",
    },
    {
        "id": null,
        "name": null,
        "adsFactId": "743158",
    },
    {
        "id": null,
        "name": null,
        "adsFactId": "743159",
    },
    {
        "id": null,
        "name": null,
        "adsFactId": "743976",
    },
    {
        "id": null,
        "name": null,
        "adsFactId": "744961",
    },
    {
        "id": null,
        "name": null,
        "adsFactId": "746809"
    },
    {
        "id": null,
        "name": null,
        "adsFactId": "747229"
    },
    {
        "adsId": null,
        "name": null,
        "adsFactId": "747231"
    },
    {
        "id": null,
        "name": null,
        "adsFactId": "749059"
    }
];

arr.some(obj => {
  if(factArr.includes(obj['adsFactId'])) {
    obj.checked = true;
    obj.checkBoxPatched = true;
  } else {
    obj.checked = false;
    obj.checkBoxPatched = false;
  }
});
console.log(arr);
