The Code

                
// get the start and end values from the page
// entry point of our application 
function getValues() {
  let startValue = document.getElementById("startValue").value; // startValue = "0"
  let endValue = document.getElementById("endValue").value; // startValue = "100"

  let startNumber = parseInt(startValue); //startNumber = 0
  let endNumber = parseInt(endValue); // startNumber = 100

  let numberArray = generateNumbers(startNumber, endNumber);
  displayNumbers(numberArray)
}

// generate the range of numbers to display
// Business/logic function
function generateNumbers(start, end) {

  let basketOfNumbers = [];

  for (let number = start; number <= end; number = number + 1) {
    basketOfNumbers.push(number); //[0, 1, 2, 3, ..., 100]
  }

  return basketOfNumbers;

}

// placing the generated numbers on the page and bolding the even numbers
// view function
function displayNumbers(numbers){
  // start = 10, end = 15
  // numbers = [10, 11, 12, 13, 14, 15]
  // numbers.length = 6 

  let results = '';

  for (let index = 0; index < numbers.length; index = index + 1){
    let currentNumber = numbers[index];

    if (currentNumber % 2 == 0){
        results += `<tr><td class="evenNumber">${currentNumber}</td></tr>`;
    } else {
        results += `<tr><td>${currentNumber}</td></tr>`;
    }



  }

  let tableBody = document.getElementById('results')
  tableBody.innerHTML = results;
}
                
            

the code is structed in three functions

• getValues
• generateNumbers
• displayNumbers

getValues uses your inputed start and end number and converts the string into a number using parseInt. It then passes the numbers to the generateNumbers function to create a the range of numbers and convert them into an array using a for loop that adds 1 until the end number is reached. generateNumbers then returns the array back to getValues sends them to the displayNumbers function. displayNumbers then uses the amount of items in the array to pick the current number and uses an if statement to decided if the number is even and give it the CSS class of evenNumber, if else it doesn't reacieve a class
