how to extract list of ids from changing array field in java script?

February 21, 2022

I am writing tests in postman and I would like to extract the list of Ids inside variants object matching condition where stock.available ==true and quantity > 3. However my issues lies that number inside variants object is random value which is 194922428018, 194922428025 and 194922428032. Final output should results only 194922428025 and 194922428032 which are the items with stock. Thanks in Advance.

[{
    "appIdentifier": "53443434w-813f-4b59-b58a-deaf76847845",
    "categoryIds": null,
    "id": "205148",
    "variants": {
        "194922428018": {
            "id": "194922428018",
            "filterAttributes": null,
            "stock": {
                "available": false,
                "lowOnStock": true,
                "leadTime": null,
                "quantity": 0
            },
            "categoryIds": null
        },
        "194922428025": {
            "id": "194922428025",
            "filterAttributes": null,
            "stock": {
                "available": true,
                "lowOnStock": true,
                "leadTime": null,
                "quantity": 9
            },
            "categoryIds": null
        },
        "194922428032": {
            "id": "194922428032",
            "filterAttributes": null,
            "stock": {
                "available": true,
                "lowOnStock": false,
                "leadTime": null,
                "quantity": 33
            },
            "categoryIds": null
        }
}]

Hope this would work for you

const testArray = [{
    "appIdentifier": "53443434w-813f-4b59-b58a-deaf76847845",
    "categoryIds": null,
    "id": "205148",
    "variants": {
        "194922428018": {
            "id": "194922428018",
            "filterAttributes": null,
            "stock": {
                "available": false,
                "lowOnStock": true,
                "leadTime": null,
                "quantity": 0
            },
            "categoryIds": null
        },
        "194922428025": {
            "id": "194922428025",
            "filterAttributes": null,
            "stock": {
                "available": true,
                "lowOnStock": true,
                "leadTime": null,
                "quantity": 9
            },
            "categoryIds": null
        },
        "194922428032": {
            "id": "194922428032",
            "filterAttributes": null,
            "stock": {
                "available": true,
                "lowOnStock": false,
                "leadTime": null,
                "quantity": 33
            },
            "categoryIds": null
        }
}}
]

const ids = Object.entries(testArray[0]['variants']).reduce((acc, [key, value])=>{
    if(value.stock.available && value.stock.quantity > 3) acc.push(key)
  return acc
}, [])

console.log(ids) // ["194922428025", "194922428032"]
