I’ve below code snippet
const arr = [
{
"name": "Attestation Component 1",
"values": [
{
"component": "Attestation Component 1"
},
{
"component": "Attestation Component 1"
},
{
"component": "Attestation Component 1",
}
]
},
{
"name": "Attestation Component 2",
"values": [
{
"id": "10005884",
"url": "https://www.msn.com",
"bfaId": "G44.5.3.1N/A",
"component": "Attestation Component 2"
},
{
"id": "10005883",
"url": "https://www.hotmail.com",
"bfaId": "G44.5.3.2N/A",
"component": "Attestation Component 2"
}
]
},
{
"name": "Attestation Component 3",
"values": [
{
"id": "10005882",
"url": "https://www.rediffmail.com",
"bfaId": "G44.5.3.3N/A",
"component": "Attestation Component 3"
}
]
}
]
const bool = arr.map(group => group.values.every(val => val.id));
console.log(bool);I’ve three object with name Attestation Component 1, Attestation Component 2 ,Attestation Component 3. I’m getting the expected output as false, true, true. What’s the reason for this? I want to add the property to the existing array of object as something isInvalid: true/false below name
Expected O/P (add property in each object with below key value pairs)
isInvalid: true/false
>Solution :
That is because your algorithm is incorrect. The every method will check if all the objects have an id, but that is not what you want right ?
So try this instead
const bool = arr.map(group => group.values.some(val => val.id)).filter(bool => !bool).toString();
