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;
}

Here's a refactored version of the code with improvements for readability:

```javascript
// Iterate over the list and double each element
list.forEach((value) => {
  value *= 2;
});
```

Here are the improvements made:

1. **Simplified syntax**: Using `forEach` is a more modern and idiomatic way to iterate over an array in JavaScript.

2. **Removed unnecessary variable**: The `i` variable is not necessary in this case, as we can directly access the current element using the `value` variable.

3. **Consistent spacing**: The code has consistent spacing between lines and statements.

4. **Improved variable naming**: Using `value` as the variable name is more descriptive than `list[i]`. This also follows the conventional naming style of using camelCase for variable names in JavaScript.

This refactored code is more readable, maintainable, and efficient, and it's also more idiomatic in JavaScript.
