How to use

npm install range-array-to-string

const RangeArrayToString = require('range-array-to-string');

const rats = new RangeArrayToString();

rats.range([1, 2, 3, 5, 6, 7, 20])
    .then((string) => {
        // >> '1-3,5-7,20'
    })
    .catch((err) => {
        // handle error

rats.range([44, 20, 1, 2, 3, 5, 6, 7])
    .then((string) => {
        // >> '1-3,5-7,20,44'
    })
