Immutable Discontinuous Range
Wrapper for the excellent npm package
DRange
.
This wrapper keeps the exact same API syntax as DRange
, except:
- each method that mutates the range, instead returns a mutated clone,
- the range is also sorted after
.add()
is used, instead of putting loose ranges at the end.
The immutability makes it fit better with a purely functional code style.
Installation
You need to install drange
yourself, so you can upgrade to newer
versions without me having to upgrade this wrapper too :)
yarn add drange drange-immutable # or npm install --save drange drange-immutable
Usage
const range = // orconst range =
Example:
const hundred = console // [ 1-100 ] const split = hundredconsole // [ 1-49, 61-100 ]console // [ 1-100 ] // ^^ still the same. // Original drange would have // mutated 'hundred' too.
