Tell us what’s happening:
am i using the && operators wrong? thanks

Your code so far


function largestOfFour(arr) {
var forest=[]
for(var i=0 ; i<arr.length;i++){
if(arr[i][0]>(arr[i][1]) && (arr[i][2]) && (arr[i][3])){
forest.push(arr[i][0]);
}
else if(arr[i][1]>(arr[i][2]) && (arr[i][3])){
forest.push(arr[i][1])
}
else if(arr[i][2]>arr[i][3]){
forest.push(arr[i][2])
}
else{
forest.push(arr[i][3])}

}
return forest;
}

largestOfFour([[17, 23, 25, 12], [25, 26, 34, 48], [4, -10, 18, 21], [-72, -3, -17, -10]]);
console.log(largestOfFour([[17, 23, 25, 12], [25, 24, 34, 48], [4, -10, 18, 21], [-72, -3, -17, -10]]))

Challenge: Return Largest Numbers in Arrays

Link to the challenge:

2 
if(arr[i][0]>(arr[i][1]) && (arr[i][2]) && (arr[i][3])){

What this translates to is:
“If arr[i][0] is greater than arr[i][1] ,
and arr[i][2] is truthy,
and arr[i][3] is truthy”

&& operators don’t refer back to the earlier > operator.
