Your code so far
Hi. I have tested this code on my browser, on https://ronakshah.net/console/ and result is Ok, but on freeCodeCamp I get “TypeError: unknown: Cannot read property ‘0’ of undefined”.
What is the matter?
Please, who can explain me.
function getIndexToIns(arr, num) {
// Find my place in this sorted array.
arr1 = arr.concat(num);
arr2 = arr1.sort((x,y)=>x-y);
for(var i = 0; i<arr2.length; i++)
if(arr2[i]===num)
return i;
}
getIndexToIns([40, 60], 50);

On your for loop you need to put the {} at the end of it and pass the if statement in there. I would just put the return on the same line as the if statement as well. You also need to define arr1 and arr2.
I got it to pass like this
function getIndexToIns(arr, num) {
// Find my place in this sorted array.
let arr1 = arr.concat(num); //Define this variable
let arr2 = arr1.sort((x,y)=>x-y); //This one too
for(var i = 0; i<arr2.length; i++){ //<-Don't forget the curly braces
if(arr2[i]===num) return i //Pass the if statement inside the curly braces of the for loop
}
}
getIndexToIns([40, 60], 50);
function getIndexToIns(arr, num) {
// Find my place in this sorted array.
var arr1 = arr.concat(num);
var arr2 = arr1.sort((x,y)=>x-y);
for(var i = 0; i<arr2.length; i++){
if(arr2[i]===num)
return i;
}
return arr2.length;
}
getIndexToIns([40, 60], 50);
