Instead of “return arr.length”, why can’t I use “return i” to get the results? Anybody can help me with this, thanks!
Question goes like this:
Where do I Belong
Return the lowest index at which a value (second argument) should be inserted into an array (first argument) once it has been sorted. The returned value should be a number.
For example, getIndexToIns([1,2,3,4], 1.5)
should return 1
because it is greater than 1
(index 0), but less than 2
(index 1).
Likewise, getIndexToIns([20,3,5], 19)
should return 2
because once the array has been sorted it will look like [3,5,20]
and 19
is less than 20
(index 2) and greater than 5
(index 1).
**Your code so far**
function getIndexToIns(arr, num) {
arr.sort((a, b) => a - b);
for (let i = 0; i < arr.length; i++){
if (arr[i] >= num){
return i
}
}
return arr.length;// why can't I use "return i", and why he use "return arr.length" to get the index of num?
}
getIndexToIns([40, 60], 50);
