Javascript Closures - Unable to save copy of "count' within an IIFE function -


so have global var called count changes 0 4 in between 2 function declarations (see myfuncs array).

i want create closure , save copy of count of 0 1st function , 4 in 2nd function.

somehow, though i'm using iife (immediately invoked function expressions) create new lexical scope , saving copy of count (as j), still both pointing count = 4 , when functions executed, first , second function both print out "my value: 4" twice when expected:

"my value: 0" "my value: 4"

var myfuncs = {};  var count = 0;  myfuncs[0] = function(){     (function(){         var j = count; //create closure on count value , save inside iife scope         console.log("my value: " + j); //expecting j 0     })(); }  count = 4;  //update value inbetween 2 function declarations  //same above j here should 4 myfuncs[1] = function(){     (function(){         var j = count; //create closure on count value , save inside iife scope         console.log("my value: " + j);     })(); }  myfuncs[0](); //my value: 4 myfuncs[1](); //my value: 4

you're not creating closure variable, because refer in function. needs passed in, , passed in value needs used.

        myfuncs[0] = function(j){             return function(){                 console.log("my value: " + j);             };         }(count);
