javascript - Error on second level object for nodejs response -


i have situation.., i'm making this:

app.post('someurl', function (req, res) {      var r = res.data;      var = {};     a.name = r.name || "",     a.someotherkey : {         id: r.otherkey.id || ""     }  });

the thing when res.data == "", can assign value of a.name because r.name "undefined", r.otherkey.id horrible 

"typeerror: cannot read property 'id' of undefined"

any ideas solve problem ???

you take advantage of && operator do:

a.someotherkey = {     id: r.otherkey && r.otherkey.id || "" }

&& return second value if both true, , false if 1 (or both) false.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
