Can't figure out how to loop thru an array (or object) with a "if(count > n)".  Here's some sample code:

var myObj = {"first":"hello", "second":"goodbye", "third":"adios", "fourth":"bonjour", "fifth":"later"};
var length = Object.keys(myObj).length;
console.log(length);   // returns 5

var count = 0;
var myarray = [];

for (key in myObj) {
     if (count < 2) {
          myarray.push(key);
          count++;
     }
}
console.log(myarray);   // returns ["first", "second"]

but if I try to test where count ">" a value, it fails??,  for example:

for (key in myObj) {
     if (count > 2) {
           myarray.push(key);
          count++;
     }
}
it returns empty array "[]"

what the heck am I doing wrong??? thanks in advance!

dont' forget to reset your vars : http://jsfiddle.net/2pk8F/1/
var myObj = {"first":"hello", "second":"goodbye", "third":"adios", "fourth":"bonjour", "fifth":"later"};
var length = Object.keys(myObj).length;
console.log(length);   // returns 5

var count = 0;
var myarray = [];

for (key in myObj) {
     if (count < 2) {
          myarray.push(key);
          count++;
     }
}
console.log(myarray);   // returns ["first", "second"]

//but if I try to test where count ">" a value, it fails??,  for example:

count = 0; // don't forget to reset it
myarray = [];// don't forget to reset it
for (key in myObj) {
    if (count > 2) {
        myarray.push(key);
    }
    count++;
}
console.log(myarray);   // returns ["fourth", "fifth"]
