Sample Solution:

JavaScript Code:

// Define a function named near_100 with parameters x and y
function near_100(x, y) {
  // Check if x is not equal to y
  if (x != y) {
    // Calculate the absolute difference between x and 100, store it in x1
    x1 = Math.abs(x - 100);

    // Calculate the absolute difference between y and 100, store it in y1
    y1 = Math.abs(y - 100);

    // Compare x1 and y1 to determine which value is closer to 100
    if (x1 < y1) {
      // Return x if x is closer to 100
      return x;
    }

    // Return y if y is closer to 100
    if (y1 < x1) {
      return y;
    }

    // Return 0 if x and y are equidistant from 100
    return 0;
  } else {
    // Return false if x is equal to y
    return false;
  }
}

// Log the result of calling near_100 with the arguments 90 and 89 to the console
console.log(near_100(90, 89));

// Log the result of calling near_100 with the arguments -90 and -89 to the console
console.log(near_100(-90, -89));

// Log the result of calling near_100 with the arguments 90 and 90 to the console
console.log(near_100(90, 90));

Output:

90
-89
false

ES6 Version:

// Define a function named near_100 with parameters x and y
const near_100 = (x, y) => {
  // Check if x is not equal to y
  if (x !== y) {
    // Calculate the absolute difference between x and 100, store it in x1
    const x1 = Math.abs(x - 100);

    // Calculate the absolute difference between y and 100, store it in y1
    const y1 = Math.abs(y - 100);

    // Compare x1 and y1 to determine which value is closer to 100
    if (x1 < y1) {
      // Return x if x is closer to 100
      return x;
    }

    // Return y if y is closer to 100
    if (y1 < x1) {
      return y;
    }

    // Return 0 if x and y are equidistant from 100
    return 0;
  } else {
    // Return false if x is equal to y
    return false;
  }
};

// Log the result of calling near_100 with the arguments 90 and 89 to the console
console.log(near_100(90, 89));

// Log the result of calling near_100 with the arguments -90 and -89 to the console
console.log(near_100(-90, -89));

// Log the result of calling near_100 with the arguments 90 and 90 to the console
console.log(near_100(90, 90));
