Transform an array of object's designated key values into a string that is separated by commas

Is there a way to convert specific key values of an object into a comma-separated string? I have been able to do this with arrays, but my current challenge is that my data is an array of objects. I want to convert each 'id' value into an array of strings as shown in the example below.

#current code - just initial idea

console.log(['a', 'b', 'c'].join(','));

#example object

data = [
    {
        "id": 496,
    },
    {
        "id": 381,
    }
]

#expected result

'496,381'

Answer №1

To retrieve the values of the id key from an array of objects, you can use the map method:

The map() function generates a new array by applying a specified function to each element in the original array.

data.map(item => item.id).join()
