Why can't I save the modified mongoose object?

Question

JavaScript

const dbObjects = await Model.find({ b })

    for (const obj of parsedObjects) {
        const dbObject = dbObjects.find(elem => elem.id === obj.id)

        if(!dbObject) {
            //dbObjects.shift(obj)
        } else if(!(dbObject.e.length === obj.e.length)){
            dbObject.e = obj.e
            console.log(dbObjects)
        }
    }

    await dbObjects.save()

Why does dbObjects.save is not a function give an error?

Answer 1

.find() will return an array even if there is only one document, and an empty array if none is found, and an array cannot be .save()

for (const obj of parsedObjects) {
        const dbObject = dbObjects.find(elem => elem.id === obj.id)
         .....
        // а вот здесь наверно получится
        await dbObject.save()
    }
