Writing a JavaScript function to convert months into years and months

Greetings, fellow programmer! We'll walk you through a JavaScript function that can convert months into years and months. This simple yet effective function can prove very useful during your coding journey. Once you learn it, you'll have another efficient tool in your programming arsenal. Keep reading and happy coding!

Step 1

The first step is to declare a function. Let's name it 'convertMonthsToYearsAndMonths'. This function takes a single parameter, which is the number of months you want to convert into years and months.

function convertMonthsToYearsAndMonths(months) {

}

Step 2

Inside the function, calculate the number of years by dividing the total number of months by 12. As we want to consider only full years, we use the Math.floor method, which returns the largest integer less than or equal to a given number.

function convertMonthsToYearsAndMonths(months) {
  var years = Math.floor(months / 12);
}

Step 3

The remaining months can be calculated by getting the remainder of the division of the total number of months by 12. We can do this by using the modulus operator (%).

function convertMonthsToYearsAndMonths(months) {
  var years = Math.floor(months / 12);
  var remainingMonths = months % 12;
}

Step 4

Now that we've calculated the years and the remaining months, we can return these values from the function. The return value will be a string that says 'X years and Y months' where X and Y are the years and remaining months respectively.

function convertMonthsToYearsAndMonths(months) {
  var years = Math.floor(months / 12);
  var remainingMonths = months % 12;
  return years + ' years and ' + remainingMonths + ' months';
}

Conclusion

And there you have it! A function that takes a number of months and returns a string representing those months in years and months. Here's the final code:

function convertMonthsToYearsAndMonths(months) {
  var years = Math.floor(months / 12);
  var remainingMonths = months % 12;
  return years + ' years and ' + remainingMonths + ' months';
}

Mathematical principle

The function works on the principle of division and modulus operations. With the input of months, we divide it by 12 to get the total years as `years = months / 12`, and the remainder gives us the remaining months `remaining_months = months % 12`.
