Sort and reverse method in JavaScript

Sort and reverse method in JavaScript
### Sorting in JavaScript

Sorting is the process of arranging elements in a particular order. In JavaScript, the `sort()` method is used to sort the elements of an array. By default, it sorts the elements as strings in ascending order. If the elements are numbers, they are converted to strings and then compared.

**Key Points:**
- The `sort()` method modifies the original array.
- It converts elements to strings and sorts them lexicographically by default.
- To sort numbers or use a custom sorting logic, a compare function can be provided.

**Example Cases:**
- **Alphabetical Sorting:** ["banana", "apple", "cherry"] becomes ["apple", "banana", "cherry"].
- **Numerical Sorting (default):** [30, 4, 12] becomes [12, 30, 4] (since it's sorted as ["12", "30", "4"]).

**Using Compare Function:**
- A compare function can be provided to sort numbers or custom objects properly.
- The compare function should return a negative, zero, or positive value based on whether the first argument is less than, equal to, or greater than the second argument.

### Reversing in JavaScript

Reversing is the process of changing the order of elements to be in the opposite direction. In JavaScript, the `reverse()` method is used to reverse the elements of an array.

**Key Points:**
- The `reverse()` method modifies the original array.
- It rearranges the elements in place, swapping the first with the last, the second with the second-to-last, and so on.

**Example Cases:**
- **Basic Reversing:** [1, 2, 3] becomes [3, 2, 1].
- **String Reversing:** ["a", "b", "c"] becomes ["c", "b", "a"].

### Practical Usage

Sorting and reversing are often used together in data processing:
- **Sorting and then Reversing:** To sort an array in descending order, you can first sort it in ascending order using `sort()` and then reverse it using `reverse()`.
- **Combined Operations:** Useful for displaying lists in a specific order, such as alphabetical or numerical order, and then reversing for alternate displays.
