A vanila js, heavy tested, library to manage a list of ranges.
- a list of range is : [ [a,b], [c, d], ... [m,n] ]
- where a < b < c ... < m < n
- add the following files to your code (no other dependencies) :
./src/linked-list.js./src/range-list.js
- Exemple :
const RangeList = require('../src/range-list')
const list = new RangeList()
list.addRange(10,20)
list.addRange(15,25)
list.addRange(-10,5)
// get an array of all ranges
console.log( list.ranges() )
// [[-10,5], [10,25]]-
addRange (a, b)- add a range [a,b] to the list. Indexes can be Integers or Flot, positive or negative.
- Can overlap an existing range, will unifomize so that in the end there is no overlaping.
-
ranges ()- returns an array of all ranges [[a,b], ... , [c,d]]
