I must determine whether the contents of an array exceed zero

Question

I must determine whether the contents of an array exceed zero

THE SUMMARY:

I have three value numbers for an array. If the total addition of the array's elements is greater than 0, I need to display "el funcionamiento no es infinito", otherwise "es infinito".

It seems that it's not working because I believe I am not calculating all elements in the array danio_Total.

BELOW IS THE CODE. THANK YOU!

var checkFunctioningTime = function(i) {

    if (danio_Total.value > 0) {
        document.write("el funcionamiento no es infinito");
    } else {
        document.write("El tiempo de funcionamiento es infinito");
    }

}

Answer №1

Understanding this concept is simpler than it may seem. If you have an array and your goal is to determine if the sum is greater than zero, you can approach it by considering that the sum would only equal zero if all values in the array are zero (unless negative numbers are present).

[0,0,0,0]

This specific type of array will result in a sum of zero.

Since zeros evaluate as false, you can use the following logic:

if ( sampleArray.filter(Boolean).length ) {
    document.write("The operation is not infinite");
} else {
    document.write("The operation time is infinite");
}

When using Boolean filtering, any positive integer is considered true, hence:

[0,0,9].filter(Boolean).length; // returns 1, true
[0,3,9].filter(Boolean).length; // returns 2, true
[0,0,0].filter(Boolean).length; // returns 0, false

This method simplifies the process effectively.

Answer №2

Give this method a shot

 let sum = numbers.reduce(function(accumulator, currentValue){
                 return accumulator + currentValue;
             });

 if (sum > 0) {
    document.write("The operation is not infinite");
} else {document.write("The operation time is infinite");}

Give this method a shot

 let sum = numbers.reduce(function(accumulator, currentValue){
                 return accumulator + currentValue;
             });

 if (sum > 0) {
    document.write("The operation is not infinite");
} else {document.write("The operation time is infinite");}

To determine the size of an array, you can use the following method:

   for (i = 0; i < arr.length; i++){
    total += arr[i]; 
   }

Answer 6

To determine the size of an array, you can use the following method:

   for (i = 0; i < arr.length; i++){
    total += arr[i]; 
   }
