Sort natural number index ranges [ [5, 6], [1, 3] ] => [ [1, 3], [5, 6] ]

Package Exports

  • ranges-sort

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ranges-sort) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Rationale

It sorts the array of index arrays, for example:

[ [5, 6], [1, 3] ] => [ [1, 3], [5, 6] ]
[ [5, 6], [5, 3], [5, 0] ] => [ [5, 0], [5, 3], [5, 6] ]
[] => []

[[1, 2], []] => // throws, because there's at least one empty range
[['a']] => // throws, because range is not a range but a string
[[1], [2]] => // throws, because one index is not a range

// 3rd argument and onwards are ignored:
[[3, 4, 'aaa', 'bbb'], [1, 2, 'zzz']] => [[1, 2, 'zzz'], [3, 4, 'aaa', 'bbb']]

API

rangesSort(arr[, opts])

Input argument Type Obligatory? Description
arrOfRanges Plain object yes Array of zero or more arrays meaning natural number ranges (2 elements each)
opts Plain object no Optional options go here.

For example,

[ [5, 9], [5, 3] ] => [ [5, 3], [5, 9] ]

This package does not mutate the input array.

Options object

options object's key Type Obligatory? Default Description
{
strictlyTwoElementsInRangeArrays Boolean no false If set to true, all ranges must have two and only elements, otherwise error is thrown. For example, input being [ [1, 2, 'zzz'] ] would throw (3 elements), as well as [ ['a'] ] (1 element).
}

Output: Sorted input array. First, we sort by the first argument of each child range array, then by second.
