simplifyRanges(ranges: number[][], options?: object): number[][]

The function takes an array of closed integer ranges.

Normalizes reversed ranges by converting them from [3, 1] to [1, 3] and also supports negative numbers.

options

Type: object

separateTwoNumberRanges

Type: boolean
Default: false

Separate two-number ranges [[1, 2], [4, 5]] into individual ranges [[1, 1], [2, 2], [4, 4], [5, 5]].

This can be useful if you have special handling for single-number ranges.
