🏋🏻 A small and powerful library for creating ranges of almost anything: numbers, letters, dates and even strings! Yay!
$ npm install power-range
Creates an array with the range between two values.
const pr = require('power-range');
// Number ranges
pr.create(0, 5);
//=> [0, 1, 2, 3, 4 ,5]
pr.create(-2, 5);
//=> [-2, -1, 0, 1 , 2, 3, 4, 5]
pr.create(100, 100);
//=> [100]
// Options
/**
* increment: The interval between the range values
*/
pr.create(2, 10, { increment: 2 });
//=> [2, 4, 6, 8, 10]
pr.create(-2, 13, { increment: 3 });
//=> [-2, 1, 4, 7, 13]
// Date ranges
pr.create(new Date(2001, 2, 30, 4, 5, 6), new Date(2001, 3, 2, 6, 7, 8));
