javascript - Backbone underscore lamba or conditional branching? -


very new backbone , js , have following statement created branch on logic:

        if (config.version !== 'undefined') {             mgr.useviews().setviews({});  /** hide div1 view layout **/         } else {             mgr.useviews().setviews({     /** show div1 view layout **/                 '#div1': new div1view({                     model: mydiv1model                 })             });                         }

what more effective way use lambda or construct within setviews() method instead of wrapping entirely if statement?

something like:

            mgr.useviews().setviews({                /** if (config.version === 'undefined') {**/ <= not sure be?                                   '#div1': new div1view({                     model: mydiv1model                 })               /** } **/             });

you need conditional expression

var views = (config.version !== 'undefined') ? {} : {             '#div1': new div1view({                 model: mydiv1model             })         };  mgr.useviews().setviews(views);

related: sure want check string 'undefined'?

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.
