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:
Suggest the most efficient way to improve the following code:

### Input:
def get_areas():
    areas = []
    for x in range(4):
        for y in range(4):
            area = x * y
            areas.append(area)
    return areas

### Response:
def get_areas():
    return [x * y for x in range(4) for y in range(4)]

This uses a list comprehension to generate the list of areas in one line, instead of nested loops and an appending loop. This is much more efficient and concise.
