.add(range_array, from_range_arrays) ⇒ Array of MonthRange::MRange

Union range

Examples:

from_range_arrays

from_range_arrays = [
  [Date.parse('2020-01-01'), Date.parse('2020-04-01')],
  [Date.parse('2020-07-01'), Date.parse('2020-10-01')],

]

Simple

range_array = [Date.parse('2020-03-01'), Date.parse('2020-05-01')]
MonthRange::Service.add(range_array, from_range_arrays)

#=> [[#<Date: 2020-01-01 ((2458850j,0s,0n),+0s,2299161j)>, #<Date: 2020-05-01 ((2458971j,0s,0n),+0s,2299161j)>], [#<Date: 2020-07-01 ((2459032j,0s,0n),+0s,2299161j)>, #<Date: 2020-10-01 ((2459124j,0s,0n),+0s,2299161j)>], [#<Date: 2020-12-01 ((2459185j,0s,0n),+0s,2299161j)>, nil]]
