Writing a JavaScript Function to Convert Minutes into Hours and Minutes

Hello there, fellow programmer! In this post, we'll be going through a simple yet practical JavaScript function, convertMinutesToHoursAndMinutes. This function comes in handy when we need to convert a given number of minutes into hours and minutes format. As we walk through the composition of this function, you'll get to strengthen your grasp on JavaScript's fundamental concepts. Looking forward to your coding prowess growing even stronger!

Step 1: Define the function and the parameter:

To start, we need to define our function and give it a name; convertMinutesToHoursAndMinutes seems appropriate as it clearly indicates the role of the function. Also, we have to specify one parameter, which is the total number of minutes to convert.

function convertMinutesToHoursAndMinutes(minutes){
  // function body will go here
}

Step 2: Use the Math.floor() function to calculate the number of hours:

JavaScript provides a function named Math.floor(). This function returns the largest integer less than or equal to a given number. We can use it to compute the number of full hours in the given number of minutes.

function convertMinutesToHoursAndMinutes(minutes){
  const hours = Math.floor(minutes / 60);
}

Step 3: Calculate the remaining minutes:

Next, we calculate the number of remaining minutes after we have subtracted the full hours. In JavaScript, we use the modulus operator % to get the remainder of a division.

function convertMinutesToHoursAndMinutes(minutes){
  const hours = Math.floor(minutes / 60);
  const remainingMinutes = minutes % 60;
}

Step 4: Return the results in the desired format:

The final step is to return the calculated hours and remaining minutes in the desired format. In this case, we`ll return a string that says "x hours and y minutes".

function convertMinutesToHoursAndMinutes(minutes){
  const hours = Math.floor(minutes / 60);
  const remainingMinutes = minutes % 60;
  return `${hours} hours and ${remainingMinutes} minutes`;
}

Conclusion:

In this article, we learned how to write a JavaScript function that converts a given number of minutes into hours and minutes. This function can be very useful in various time computation and manipulation tasks. Here we used division to obtain the hours and the modulus operator to obtain the remaining minutes. Then, we used template literals to return the result in the form we needed. Here is the complete code:

function convertMinutesToHoursAndMinutes(minutes){
  const hours = Math.floor(minutes / 60);
  const remainingMinutes = minutes % 60;
  return `${hours} hours and ${remainingMinutes} minutes`;
}

Mathematical principle

This function operates based on the mathematical principle of division. It divides the number of minutes by `60` to obtain the number of hours, and the remainder (modulo operation `%`) is the left number of minutes. For instance, if we have `61` minutes, dividing by `60` gives `1` hour and `1` minute as remainder.
