Creating, Modifying, and Sorting an Array in JavaScript

To achieve the desired outcome of creating an array, replacing negative elements with their absolute values, and sorting the array in non-decreasing order, you can follow these steps in JavaScript:

1. Create a Random Array: - Use the `Math.random()` function to generate random numbers and populate an array with them.

   // Create a random array of 10 elements
   let randomArray = Array.from({ length: 10 }, () => Math.floor(Math.random() * 20) - 10);
   

2. Replace Negative Elements with Absolute Values: - Iterate through the array and replace negative elements with their absolute values using the `Math.abs()` function.

   // Replace negative elements with their absolute values
   randomArray = randomArray.map(num => num < 0 ? Math.abs(num) : num);
   

3. Sort the Array in Non-Decreasing Order: - Use the `Array.prototype.sort()` method to sort the array in non-decreasing order.

   // Sort the array in non-decreasing order
   randomArray.sort((a, b) => a - b);
   

4. Display the Original and Modified Arrays: - Output the original and modified arrays to the console for comparison.

   // Display the original and modified arrays
   console.log('Original Array:', randomArray);
   

   // Display the modified array after replacing negative elements and sorting
   console.log('Modified Array:', randomArray);
   

By following these steps, you can create a random array, replace negative elements with their absolute values, sort the array in non-decreasing order, and display both the original and modified arrays for comparison.
