Suggest the most efficient way to improve the following code:
def get_areas():
    areas = []
    for x in range(4):
        for y in range(4):
            area = x * y
            areas.append(area)
    return areas
One way to improve the efficiency of the code is to utilize list comprehension to reduce the number of lines of code and improve readability. The improved code would look like this:

def get_areas():
    areas = [x * y for x in range(4) for y in range(4)]
    return areas
