JavaScript: Get the difference between a given number

JavaScript Basic: Exercise-15 with Solution

Write a JavaScript program to get the difference between a given number and 13, if the number is broader than 13 return double the absolute difference.

Sample Solution:

JavaScript Code:

// Define a function named difference that takes a parameter n
function difference(n) {
    // Check if n is less than or equal to 13
    if (n <= 13) {
        // If true, return the difference between 13 and n
        return 13 - n;
    } else {
        // If false, return the double of the difference between n and 13
        return (n - 13) * 2;
    }
}

// Log the result of calling the difference function with the argument 32 to the console
console.log(difference(32));

// Log the result of calling the difference function with the argument 11 to the console
console.log(difference(11)); 

Output:

38
2

See the Pen JavaScript: Number difference - basic-ex-15 by w3resource (@w3resource) on CodePen.

ES6 Version:

 // Difference function using arrow function
const difference = (n) => {
  return n <= 13 ? 13 - n : (n - 13) * 2;
};

// Example usage
console.log(difference(32));
console.log(difference(11));
