range Create an array containing a range of elements arrayrange mixedlow mixedhigh intstep range returns an array of elements from low to high, inclusive. If low > high, the sequence will be from high to low. If a step value is given, it will be used as the increment between elements in the sequence. step should be given as a positive number. If not specified, step will default to 1. Prior to version 4.1.0 the range function only generated incrementing integer arrays. Support for character sequences and decrementing arrays was added in 4.1.0. The step parameter was added in 4.4.0. See shuffle for another example of its use.
