Why does this log out to the console

var result = ""; for (var i = 4; i <= 156; i += 4) { result += i + " "; } console.log(result);

script.js 
var result = "";
for (var i = 4; i <= 156; i += 4) {
  result += i + " ";
}
console.log(result);

The challenge is expecting you to log each number as a separate message, not just one message that has all the numbers.

Also, the instructions ask you to log all the numbers in the range, but if you use an increment of "i += 4" the loop code will only run for every fourth number.
