javascript - Firebase - set priority when doing an update/fanout to several nodes -

i'm writing several parts/nodes of firebase database in 1 update. possible set priority of node when doing this? example:

firebaseref.update([     "/some/node/": "value",     "/some/other/node": "other value" ]) 

what if want set priority of node @ "/some/other/node" @ same time. possible? like:

firebaseref.update([     "/some/node/": "value",     "/some/other/node": {         value: "other value",         priority:  0 - date.now()     } ]) 

you got it, "magic" property named .priority:

firebaseref.update([     "/some/node/": "value",     "/some/other/node": {         value: "other value",         ".priority":  0 - date.now()     } ] 

note there aren't lot of reasons use priorities anymore in firebase. adding named property (e.g. "reversedtimestamp": 0 - date.now()) accomplish same , less hidden/magic.

update

it seems want update node's value, not child named value. set (primitive) value , priority in 1 go, use:

firebaseref.update([     "/some/node/": "value",     "/some/other/node": {         ".value": "other value",         ".priority":  0 - date.now()     } ]);
