Answer 1

Since there is no index of your data structure by _id, something is going to have to loop over the structure and find an _id value that matches.

function findId(data, id) {
    for (var i = 0; i < data.length; i++) {
        if (data[i]._id == id) {
            return(data[i]);
        }
    }
}
