Javascript not reading array items beginning with 0 -

-

i want give genetic algorithms chance can't seem find solution problem.

this code:

var encodings = {    0000: 0,    0001: 1,    0010: 2,    0011: 3,    0100: 4,    0101: 5,    0110: 6,    0111: 7,    1000: 8,    1001: 9,    1010: "+",    1011: "-",    1100: "*",    1101: "/"  };  var chromosome = "";    (var = 0; < 36; i++) {    chromosome += math.round(math.random());  }    var chromarray = chromosome.match(/.{1,4}/g);    document.write(chromarray + "<br>");    (var o = 0; o < 9; o++) {    document.write(encodings[chromarray[o]]);  }

if run code, see there lot of undefineds in output. cause this?

thanks!

you should convert keys of object strings

it should be:

var encodings =  {   "0000": 0,   "0001": 1,   "0010": 2,   "0011": 3,   "0100": 4,   "0101": 5,   "0110": 6,   "0111": 7,   "1000": 8,   "1001": 9,   "1010": "+",   "1011": "-",   "1100": "*",   "1101": "/" };  var chromosome = "";  (var = 0; < 36; i++)  {   chromosome += math.round(math.random()); }  var chromarray = chromosome.match(/.{1,4}/g);  document.write(chromarray + "<br>");  (var o = 0; o < 9; o++)  {   document.write(encodings[chromarray[o]]); }
