I am working with two 2D arrays:
arr1 = [['2001-01-01', 100], ['2001-01-02', 105],...]
arr2 = [['2001-01-01', 100], ['2001-01-02', 120],...]
I want to determine if subtracting any of the [i][1] elements of the arrays from each other will yield a negative number. What kind of loop should I use for optimal performance and efficient code?
A for loop is the most basic way to iterate through arrays.
for (i = 0; i < arr.length; i++) {
if (arr[i][1] < secondArr[i][1]) {
console.log(arr[i][0]);
}
}
