如何检查文档参考的javascript数组中是否存在Firestore文档参考？

Question

I have a document with an array as it's field which basically stores references to other documents.

When I fetched the document data and checked if a document reference is in the array, I always get a result that it doesn't exist in the array, even if its already in there.

//The below codes logs as 'false'

console.log([db.doc('collectionName/docId')].includes(db.doc('collectionName/docId')))

console.log(db.doc('collectionName/docId') === db.doc('collectionName/docId'))

I think there is something unique with each document reference. If this is the case then how can I check if a document reference exists in an array of document references?

Answer 1

Since the document reference objects are not equal, the only way I could do it was to compare the id of the document objects, to see if they match.

This returns true :

console.log([db.doc('/collectionName/docId')]
.some(doc => doc.id === db.doc('/collectionName/docId').id));
