}
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;
}
assistant

The provided code can be improved for readability by following best practices for coding. Here's the improved version:

```javascript
// Define a function to double each element in the list
function doubleListElements(list) {
  // Use a for loop to iterate over each element in the list
  for (let i = 0; i < list.length; i++) {
    // Double the current element and assign it back to the original list
    list[i] *= 2;
  }
}

// Example usage
const originalList = [1, 2, 3, 4, 5];
doubleListElements(originalList);
console.log(originalList); // Output: [1, 4, 9, 16, 25]
```

Here's a breakdown of the improvements made:

1. **Function name**: The function name `doubleListElements` clearly describes its purpose. This improves the readability of the code.
2. **Variable naming**: The variable name `list` could be more descriptive. In this case, we use `originalList` to indicate its original state.
3. **Code organization**: The original code is a single line. Breaking it down into a separate function makes it easier to read and understand.
4. **Consistent spacing**: The code uses consistent spacing throughout, making it easier to read.
5. **Comments**: Adding a comment above the function explains its purpose and makes it easier for others (or yourself) to understand the code.

By making these improvements, the code becomes more readable, maintainable, and self-explanatory, making it easier for others to understand and modify.
