### Instruction:
How can the following code be improved for readability?

### Input:
for(let i = 0; i < list.length; i++)
{
  list[i] *=2
}

### Response:
for (let i = 0; i < list.length; i++) {
  list[i] = list[i] * 2;
}

Here's an improved version of the code for readability:

```javascript
// Initialize a new array by doubling each element in the original list
const doubledList = list.map((element) => element * 2);
```

Explanation:
- The original code was using a `for` loop with a simple assignment operation (`list[i] *= 2`), which can be hard to read for complex operations or multiple lines.
- The `map()` method is a more concise and efficient way to create a new array with doubled values. It applies a provided function to every element in the original array and returns a new array with the results.

Alternatively, you can also use the `reduce()` method for even more readable and efficient code:

```javascript
// Initialize a new array by doubling each element in the original list
const doubledList = list.reduce((acc, element) => acc * 2, 1);
```

Explanation:
- The `reduce()` method applies a provided function (in this case, multiplication by 2) to every element in the original array, starting with an initial value of 1.
