Let's implement the range function:

range([start], stop, [step])

range(1, 11);
=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

range(1, 4, 0); // /!\ note that the step is 0
=> [1, 1, 1]

range(0);
=> []

range(10, 0); // /!\ note that the end is before the start
=> []

range(10);
=> [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

range(0, 30, 5);
=> [0, 5, 10, 15, 20, 25]

start, if omitted, defaults to 0; step defaults to 1.

Returns a list of integers from start to stop, incremented by step, exclusive.

Note that ranges that stop before they start are considered to be zero-length instead of negative.
