Get a list of object names by type "Devices"

The task consists of two parts:

1. Output a string containing the object names.
2. Implement a function that forms a string with the object names (separated by commas) if their object_type belongs to types where the class field is equal to the string "Devices".

interface IObjectItem {
    id: number;
    name: string;
    object_type: number;
}

interface IObjectType {
    id: number;
    class: string;
}

const objects: IObjectItem[] = [
    { id: 1, name: "Test 1", object_type: 1 },
    { id: 2, name: "Test 2", object_type: 1 },
    { id: 3, name: "Test 3", object_type: 2 },
    { id: 4, name: "Test 4", object_type: 3 },
    { id: 5, name: "Test 5", object_type: 4 },
];

const object_types: IObjectType[] = [
    { id: 1, class: "Devices" },
    { id: 2, class: "Devices" },
    { id: 3, class: "Ports" },
    { id: 4, class: "Cables" },
];

function getNames(objects: IObjectItem[], object_types: IObjectType[]): string {
    const mapIds: number[] = [];

    object_types.forEach((type) => {
        if (type.class === "Devices") mapIds.push(type.id);
    });

    const result: string[] = [];

    objects.forEach((obj) => {
        if (mapIds.includes(obj.object_type)) result.push(obj.name);
    });

    return result.join(", ");
}

console.log(getNames(objects, object_types));
