How can I remove an element from a list, with lodash?

I have an object that looks like this:

var obj = {
    "objectiveDetailId": 285,
    "objectiveId": 29,
    "number": 1,
    "text": "x",
    "subTopics": [{
        "subTopicId": 1,
        "number": 1
    }, {
        "subTopicId": 2,
        "number": 32
    }, {
        "subTopicId": 3,
        "number": 22
    }]
}
var stToDelete = 2;

I have lodash installed in my application for other things. Is there an efficient way to use lodash to delete the entry: {"subTopicId":2, "number":32} from the obj object?

Or is there a javascript way to do this?
