convertHoursToDaysAndHours()

Step 1: Define the Function

The first step is to define a JavaScript function named convertHoursToDaysAndHours. This function will receive an argument which stands for the total number of hours we want to convert.

function convertHoursToDaysAndHours(totalHours) {}

Step 2: Calculate the Number of Days

The next step is to calculate the number of days from the total hours. Since we know that one day equals 24 hours, we can find the days by dividing the total hours by 24 and rounding down to the nearest whole number using Math.floor().

function convertHoursToDaysAndHours(totalHours) {
    var days = Math.floor(totalHours / 24);
}

Step 3: Calculate the Remaining Hours

After finding the number of days, we can calculate the remaining hours. To do this, we'll take the total number of hours and subtract the number of hours equivalent to the days we calculated earlier (days * 24). The remainder will be the hours left.

function convertHoursToDaysAndHours(totalHours) {
    var days = Math.floor(totalHours / 24);
    var remainingHours = totalHours % 24;
}

Step 4: Return the Result

Now that we have the number of days and remaining hours, let's prepare the result. We will return a string using template literals because they allow us to insert variables into strings easily. The output string will look like "X days and Y hours".

function convertHoursToDaysAndHours(totalHours) {
    var days = Math.floor(totalHours / 24);
    var remainingHours = totalHours % 24;

    return `${days} days and ${remainingHours} hours`;
}

Conclusion

Now we have a complete JavaScript function that takes a number of hours, and converts and returns it as days and remaining hours. You can call this function with any number of hours you want to convert like so:

console.log(convertHoursToDaysAndHours(30)); // "1 days and 6 hours"
