Question

Postman's ability to capture elements that meet specific criteria set by another element

Here is the output of my response code:

[
    {
        "id": 364,
        "siteName": "FX21 - PortA",
    },
    {
        "id": 364,
        "siteName": "FX21 - PortB",
    },
    {
        "id": 370,
        "siteName": "FX05 - ER",
    },

I'm trying to extract siteName values where id equals 364 and store them in an array variable using Postman. The expected array should be [FX21 - PortA, FX21 - PortB]

However, the code I've attempted so far only retrieves the first siteName value:

var requiredId = pm.response.json().find(function(element){
    if (element.id == "364"){

        return element;
    }
});

Utilize Array.filter along with a filter for the value 364 in the id property.
Then, employ Array.map to transform the filtered results into an array containing only the siteName values.
Additionally, use destructuring assignment to extract the keys of the object:

const response = [
    {
        "id": 364,
        "siteName": "FX21 - PortA",
    },
    {
        "id": 364,
        "siteName": "FX21 - PortB",
    },
    {
        "id": 370,
        "siteName": "FX05 - ER",
    }
]
function getSiteNameById(idFilter){
 return response.filter(({id}) => id === idFilter).map(({siteName}) => siteName);
}
console.log(getSiteNameById(364));

Alternatively, you can utilize Array.reduce to accomplish this task in one step by checking for the id and accumulating the elements in the final array:

const response = [
        {
            "id": 364,
            "siteName": "FX21 - PortA",
        },
        {
            "id": 364,
            "siteName": "FX21 - PortB",
        },
        {
            "id": 370,
            "siteName": "FX05 - ER",
        }
    ]
function getSiteNameById(idFilter){
 return response.reduce((acc, ele) => {
    return  ele.id === idFilter ? acc.concat(ele.siteName) : acc;
 }, []);
}
console.log(getSiteNameById(364));
