}
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 code can be improved for readability by adding comments and using more descriptive variable names. Here's a refactored version:

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

However, if you want to make it more concise and still readable, you can use the `map` function, which can handle the multiplication in a more efficient way:

```javascript
// Loop through each item in the list and multiply it by 2 using map()
list = list.map(num => num * 2);
```

This code is not only more concise but also more readable, as it clearly conveys the intention of the code.
