Usage

 //sp: {date, array, object, parse, entity, string}
const sp = require('sp-data');
sp.date.format('yyyy-MM-dd', new Date());
//=> 2018-08-06
sp.array.sort(arr = [1, 2, 3, 4, 1], isASC = true)
//=>[1, 1, 2, 3, 4]
sp.array.sort(arr = [1, 2, 3, 4, 1], isASC = false)
//=>[4, 3, 2, 1, 1]

Date

//date: format(), goto(), prevDay(), prevMonth(), prevYear(), nextDay(), nextMonth(), nextYear(), calc()
const date = require('sp-data/date');
date.format('yyyy-MM-dd', new Date());
//=> 2018-08-06
date.goto(year, month, day);
//=> return Date
date.prevDay(dayCount = 0, startDate = new Date());
//=> return Date
date.prevMonth(monthCount = 0, date = new Date());
//=> return Date
date.prevYear(yearCount = 0, date = new Date());
//=> return Date
date.nextDay(dayCount = 0, startDate = new Date());
//=> return Date
date.nextMonth(monthCount = 0, date = new Date());
//=> return Date
date.nextYear(yearCount = 0, date = new Date());
//=> return Date
date.calc(startDate = new Date(2018, 01, 01), endDate = new Date());
//=> { seconds: 20, minutes: 44, hours: 15, days: 188 }
date.calc(startDate = new Date(2018, 01, 01), endDate = new Date(2000, 01, 01));
