Tell us what’s happening:
Would someone like to explain to me what it means “(var j=0; j < arr[i].length; j++)”, the code in bold is what I don’t understand. Why should [i] be put in the “arr” of the internal loop?
I appreciate your help.
Your code so far
function multiplyAll(arr) {
var product = 1;
// Only change code below this line
for(var i=0; i < arr.length; i++){
for(var j=0; j < **arr[i].length;** j++){
console.log(arr[i][j]);
}
}
// Only change code above this line
return product;
}
// Modify values below to test your code
multiplyAll([[1,2],[3,4],[5,6,7]]);
