2. Writing a JavaScript Function to Compare Three Numbers

Creating a function to compare three numbers involves considering multiple approaches, each with its own trade-offs in terms of readability and efficiency. The goal is to create a function that not only works correctly but is also easy to understand and maintain. A well-structured function is essential for reliable number sorting.

2.1. Basic Implementation

A basic implementation involves using a series of if and else if statements to compare the numbers. This approach is straightforward but can become verbose. Despite its simplicity, it provides a clear and direct method for comparison.

function compareThreeNumbers(a, b, c) {
  if (a > b && a > c) {
    return "A is the largest";
  } else if (b > a && b > c) {
    return "B is the largest";
  } else if (c > a && c > b) {
    return "C is the largest";
  } else {
    return "Cannot determine the largest uniquely";
  }
}

console.log(compareThreeNumbers(5, 3, 8)); // Output: C is the largest
console.log(compareThreeNumbers(5, 8, 3)); // Output: B is the largest
console.log(compareThreeNumbers(8, 5, 3)); // Output: A is the largest
console.log(compareThreeNumbers(5, 5, 3)); // Output: Cannot determine the largest uniquely

Alt Text: Basic Number Comparison: A visual representation of the basic if-else structure used to compare three numbers, illustrating the decision-making process in determining the largest number.

2.2. Using `Math.max()`

JavaScript’s built-in Math.max() function can simplify the comparison. This function returns the largest of zero or more numbers. Using Math.max() leads to more concise and readable code.

function compareThreeNumbersUsingMathMax(a, b, c) {
  const largest = Math.max(a, b, c);
  if (a === largest && b === largest && c === largest) {
        return "All numbers are equal";
    }
  if (a === largest && (a == b || a == c)) {
        return "A is one of the largest numbers";
    }
  if (a === largest) {
        return "A is the largest";
    }
  if (b === largest && (b == a || b == c)) {
        return "B is one of the largest numbers";
    }
  if (b === largest) {
        return "B is the largest";
    }
  if (c === largest && (c == a || c == b)) {
        return "C is one of the largest numbers";
    }
  if (c === largest) {
        return "C is the largest";
    }
  return "Cannot determine the largest uniquely";
}

function compareThreeNumbersOptimized(a, b, c) {
  if (a > b) {
    if (a > c) {
      return "A is the largest";
    } else if (a < c) {
        return "C is the largest";
    } else {
        return "A and C are the largest";
    }
  } else if (b > c) {
    return "B is the largest";
  } else if (b < c) {
        return "C is the largest";
  } else {
        return "B and C are the largest";
  }
  return "Cannot determine the largest uniquely";
