Retrieve all objects filtered by indicated key's value

Question

I'm having a bit of a problem trying to get the exact output.

const data = [{
    name: 'Alex Young',
    country: 'SE',
    nID: 424
    address: 'some address 12'
},{
    name: 'Martha Lewis',
    country: 'PT',
    nID: 312,
    address: 'an address 49'
},{
    name: 'Sophie Jones',
    country: 'NL',
    nID: 36,
    address: 'other address 3129'
}];

const filter = '12';

const keysToEvaluate = ['name', 'country', 'address'];

For the given data, I would like to evaluate only the given keysToEvaluate and output all objects where the values contains the filter.

expected output:

[{
    name: 'Alex Young',
    country: 'SE',
    nID: 424
    address: 'some address 12'
},{
    name: 'Sophie Jones',
    country: 'NL',
    nID: 36,
    address: 'other address 3129'
}]

TIA

Basically: `const result = array.filter(entry => keysToEvaluate.some(key => entry[key].includes(filter)));` I've assumed that *any* match means the object should be included. If *all* properties should match for an object to be kept, change `some` to `every`. — T.J. Crowder, Mar 04 '20 at 15:02

    const filter = '12';

    const keysToEvaluate = ['name', 'country', 'address'];

    const filtered = data.filter(t => keysToEvaluate.some(k => String(t[k]).includes(filter)));
    console.log(filtered);

tweaked it so it becames case insensitive: ```const filtered = data.filter(t => keysToEvaluate.some(k => String(t[k].toLowerCase()).includes(filter.toLowerCase())));``` – Zé Baralho Mar 04 '20 at 15:42
