Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.

### 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;
}

The provided code can be improved for readability by adding comments to explain the purpose of the loop and the operation being performed. Here's the improved code:

```javascript
// Iterate over each element in the list and multiply it by 2
for (let i = 0; i < list.length; i++) {
  list[i] *= 2;
}
```

Alternatively, you could also use a more modern JavaScript syntax by using the `map` method, which is often preferred for its readability and efficiency:

```javascript
// Multiply each element in the list by 2 using map
list = list.map(num => num * 2);
```

This code achieves the same result as the original loop, but in a more concise and expressive way.
