_.range

_.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.

Note: JavaScript follows the IEEE-754 standard for resolving floating-point values which can produce unexpected results.
