mongoose update failed when i use var but success when i use constant?

i try to wirte a js script to pull an elem in a array in mongo.

// this one not work, which return "{ ok: 1, nModified: 0, n: 1 }"

db.userModel.updateOne({"_id":userId}, {"$pull" : {"draw.awardList":{oldActiveCode : oldTime}}}, function(err, res) ..

// this one work，

db.userModel.updateOne({"_id":userId}, {"$pull" : {"draw.awardList":{"1000812001401": 1553503004448}}}, function(err, res)

// but when i compare then, it seems equal

console.log("+++",("1000812001401" === oldActiveCode), (oldTime === 1553503004448))

output : +++ true true

{oldActiveCode : oldTime} and {"1000812001401": 1553503004448} are not the same. The former sets oldActiveCode property, and the latter sets 1000812001401 property.

If the property should be 1000812001401, it should be computed property, {[oldActiveCode] : oldTime}.
