Codecademy: Codeyear Building 'substring' (Part 2)

//sample solution

// Define substring here
var subset = "";
var substring = function(input,start,end){
var i;
//var inputLength = input.length;
for(i=start;i<=end;i++){
subset=subset+input[i];
}
return subset;
};
// Write test here:
// Call substring, passing "lorem ipsum dolor" to `input`, `6` to
// `start`, and `10` to `end`.
console.log(substring("lorem ipsum dolor",6,10));
