Answer (EN)

## 1. Via the index `length - 1` (the classic way)

This is the most universal way, and it works everywhere

```javascript
const fruits = ["apple", "banana", "cherry"];
const last = fruits[fruits.length - 1];

console.log(last); // "cherry"
```

- `length` is the array's length.
- Since indexing starts at `0`,
the last element sits at index `length - 1`.

---

## 2. Via the `.at(-1)` method (modern, ES2022+)

A nicer and more readable way

```javascript
const fruits = ["apple", "banana", "cherry"];
console.log(fruits.at(-1)); // "cherry"
```

Advantages:

- You can use **negative indexes**, like in Python.
- Works with both arrays and strings:

```javascript
  "hello".at(-1); // "o"
  ```

Supported in **Node.js 16+** and **modern browsers**.

---

## 3. Using `.slice(-1)`

```javascript
const fruits = ["apple", "banana", "cherry"];
console.log(fruits.slice(-1));  // ["cherry"]
console.log(fruits.slice(-1)[0]); // "cherry"
```

- `slice(-1)` returns a **new array** with the last element.
- To get the element itself, you need `[0]`.

---

## 4. Using destructuring (ES6+)

If you need to pull out the last element elegantly

```javascript
const fruits = ["apple", "banana", "cherry"];
const [last] = fruits.slice(-1);
console.log(last); // "cherry"
```

---

## In short:

| Method | Code | Returns | Note |
|---|---|---|---|
| Index | `arr[arr.length - 1]` | element | works everywhere |
| `.at(-1)` | `arr.at(-1)` | element | modern |
| `.slice(-1)[0]` |  | element | creates a new array |
| Destructuring | `const [last] = arr.slice(-1)` | element | elegant, ES6 |

---

> **Conclusion:**
> For cross-browser compatibility, use `arr[arr.length - 1]`.
> For modern code, `arr.at(-1)` looks much cleaner.
