<h3>45. Understanding the `.sort()` Method Variations</h3>
1472+
1473+
```js
1474+
const fruits = ["banana", "apple", "orange", "grape", "kiwi"];
1475+
1476+
// Task 1: Sort the array of fruits in alphabetical order (default behavior)
1477+
// Task 2: Sort the array of fruits in descending alphabetical order
1478+
// Task 3: Sort the array of fruits based on the length of the fruit names in ascending order
1479+
// Task 4: Sort the array of fruits in ascending order by the second character of each fruit name

Answer
1485+
1486+
Task 1: Sort in alphabetical order (default behavior)
1487+
1488+
```js
1489+
const alphabeticalOrder = [...fruits].sort();
1490+
console.log(alphabeticalOrder); // Output: ['apple', 'banana', 'grape', 'kiwi', 'orange']
1491+
```
1492+
1493+
Task 2: Sort in descending alphabetical order
1494+
1495+
```js
1496+
const descendingOrder = [...fruits].sort((a, b) => b.localeCompare(a));
1497+
console.log(descendingOrder); // Output: ['orange', 'kiwi', 'grape', 'banana', 'apple']
1498+
```
1499+
1500+
Task 3: Sort based on the length of the fruit names in ascending order
1501+
1502+
```js
1503+
const sortByLength = [...fruits].sort((a, b) => a.length - b.length);
1504+
console.log(sortByLength); // Output: ['kiwi', 'apple', 'grape', 'banana', 'orange']
1505+
```
1506+
1507+
Task 4: Sort in ascending order by the second character of each fruit name
1508+
1509+
```js
1510+
const sortBySecondChar = [...fruits].sort((a, b) => a[1].localeCompare(b[1]));
1511+
console.log(sortBySecondChar); // Output: ['banana', 'kiwi', 'apple', 'orange', 'grape']
1512+
```
1513+
1514+
Explanation:
1515+
1516+
- Task 1 utilizes the default behavior of `.sort()` to arrange elements alphabetically.
1517+
- Task 2 reverses the order by using `localeCompare()` with the reverse comparison.
1518+
- Task 3 sorts the array by the length of the elements, ensuring ascending order.
1519+
- Task 4 specifically compares the second character of each element for sorting.
1520+
1521+
These variations demonstrate different uses of the `.sort()` method by customizing the sorting logic through comparator functions, enabling diverse sorting patterns for arrays.
