Analyzing similarities between objects and arrays to find and return the matches

Items

{670: true, 671: true}

List

0: {id: 669, item_id: 35}
1: {id: 670, item_id: 35}

Desired outcome

0: {id: 670, item_id: 35}

Is there a way to compare two datasets and return the matching entries based on their ids?

Answer №1

Here is the solution you're looking for!

let object = {670: true, 671: true}
let array = [{id: 669, item_id: 35}, {id: 670, item_id: 35}]
let filteredResult = array.filter(item => object[item.id])
console.log(filteredResult)

Filtered Result:

[
    {id: 670, item_id: 35}
]
