Better approach to check property of object with another property of object in same list

I have below list in javascript –

[
 {
    "id" : 111,
    "type": "BASE",
    "someOtherProp": "other",
    "linkedId": 222
 },
 {
    "id" : 222,
    "type": "CHILD",
    "someOtherProp": "other",
    "linkedId": 111
 },
 {
    "id" : 333,
    "type": "SOMEOTHERTYPE",
    "someOtherProp": "other",
    "linkedId": 444
 }
]

I want to check in list if type === 'BASE', get the linkedId of matching type and check in same list if CHILD is present. If CHILD is not present then break the loop
and throw the exception or alert the message.

Note : BASE’s object linkedId is CHILD’s object id.

I am planning to use nested loop but looking a better approach if any for this.

Thank you.
