_.range([start=0], end, [step=1])
Creates an array of numbers (positive and/or negative) progressing from start up to, but not including, end. A step of -1 is used if a negative start is specified without an end or step. If end is not specified, it's set to start with start then set to 0.
[start=0] (number) − The start of the range.
end (number) − The end of the range.
[step=1] (number) − The value to increment or decrement by.
(Array) − Returns the range of numbers.
