Type alias Intervals

represents intervals at which slices should be performed by sliceIntervals.

• every even element dictates a start index, which should be:
  • a positive number
• every odd element dictates the subsequent end index, which can one of:
  • a positive number
  • a negative number, for reverse indexing
  • or undefined, for last element (inclusive) indexing

Example

// mathematically represents the set of intervals: { [0, 10), [20, 30), [90, Inf), [15, arr.length - 15) }
const my_intervals: Intervals = [0, 10, 20, 30, 90, undefined, 15, -15]
