Equilibrium Element

Question

/*Given an array of N positive numbers. The task is to find the position where equilibrium first occurs in the array. Equilibrium position in an array is a position such that the sum of elements before it is equal to the sum of elements after it.*/

1st
input - N=4 desire-output=-1
arr=[3,3,5,1]

2nd
input - N=5 desire-output=2
arr=[3,3,5,5,1]

function equilibriumElement(N, arr){
//write code here
for(i=0;i<N;i++){
left=0;
for(j=0;j<i;j++){
left=left+arr[j];
}
right= 0;
for(k=i+1;k<N;k++){
right=right+arr[k];
}
if(right===left){
console.log(i);
}else{
console.log(-1);
}
}
}

what i get

-1
-1
2
-1
-1

//how to get a single output?
