convertWeeksToMonthsAndWeeks()

Step 1: Define the problem

The goal is to write a JavaScript function called convertWeeksToMonthsAndWeeks, which will take in number of weeks as the input and convert it to months and weeks. As we know, one month is approximately 4.345 weeks. This function will return a string stating how many months and weeks the total weeks equate to.

let weeks = 10;

Step 2: Create basic structure of function

We start by creating our function and ensuring it can take in the weeks variable.

function convertWeeksToMonthsAndWeeks(weeks) {
}

Step 3: Implement conversion logic

Inside our function, we need to do the conversion calculation. We’ll divide the input weeks by approximately 4.345, then get the floor of this to obtain the number of months. We’ll then calculate the left over weeks.

function convertWeeksToMonthsAndWeeks(weeks) {
  var months = Math.floor(weeks / 4.345);
  var remaining_weeks = weeks % 4.345;
}

Step 4: Format and return output

We then format the string to return the calculated months and remaining weeks.

function convertWeeksToMonthsAndWeeks(weeks) {
  var months = Math.floor(weeks / 4.345);
  var remaining_weeks = Math.round(weeks % 4.345);
  return months + ' month(s) and ' + remaining_weeks + ' week(s).';
}

Step 5: Test the function

Finally, we test our function with different inputs to ensure it works as expected.

console.log(convertWeeksToMonthsAndWeeks(10)); //Outputs '2 month(s) and 1 week(s).'
console.log(convertWeeksToMonthsAndWeeks(5)); //Outputs '1 month(s) and 1 week(s).'

Conclusion:

In this article, we broke down the steps on how to convert weeks into months and weeks using Javascript. The key is in breaking down the problem into manageable parts - defining the function, implementing the conversion logic, formatting the output, then testing to check validity.
