Firebase: Priority set to null on server but not on client when setting grandchild -

to reproduce, check out http://jsfiddle.net/3ar7n/16/ . first click "set child , grandchild," sets child priority , sets grandchild within it. click "show local values" , you'll see child still seems have priority of 123. click many times - priority comes 123. once you're satisfied local priority 123, refresh whole page. you'll dismayed see priority null. i can believe concurrency issue, effects of set happening in different orders. expected behavior setting child clear priority of parent? thanks easy test case! indeed bug. client , server handling case differently, why you're seeing inconsistent behavior. note occurs if "setwithpriority" primitive value, , write deeper in tree (which deletes primitive value). update: has been fixed.

scope - Surprised that global variable has undefined value in JavaScript -

today, got surprised when saw global variable has undefined value in case. example: var value = 10; function test() { //a console.log(value); var value = 20; //b console.log(value); } test(); gives output as undefined 20 here, why javascript engine considering global value undefined . know javascript interpreted language. how able consider variables in function? is pitfall javascript engine? this phenomenon known as: javascript variable hoisting . at no point accessing global variable in function; you're ever accessing local value variable. your code equivalent following: var value = 10; function test() { var value; console.log(value); value = 20; console.log(value); } test(); still surprised you're getting undefined ? explanation: this every javascript programmer bumps sooner or later. put, whatever variables declare hoisted top of local closure. so, though declared variable after first console....
