Moment.js: Date between dates

Question

In versions 2.9+ there is an isBetween function, but it's exclusive:

var compareDate = moment("15/02/2013", "DD/MM/YYYY");
var startDate   = moment("12/01/2013", "DD/MM/YYYY");
var endDate     = moment("15/01/2013", "DD/MM/YYYY");

// omitting the optional third parameter, 'units'
compareDate.isBetween(startDate, endDate); //false in this case

There is an inclusive workaround ...
x.isBetween(a, b) || x.isSame(a) || x.isSame(b)

... which is logically equivalent to
!(x.isBefore(a) || x.isAfter(b))

In version 2.13 the isBetween function has a fourth optional parameter, inclusivity.

Use it like this:

target.isBetween(start, finish, 'days', '()') // default exclusive
target.isBetween(start, finish, 'days', '(]') // right inclusive
target.isBetween(start, finish, 'days', '[)') // left inclusive
target.isBetween(start, finish, 'days', '[]') // all inclusive

More units to consider: years, months, days, hours, minutes, seconds, milliseconds

Note: units are still optional. Use null as the third argument to disregard units in which case milliseconds is the default granularity.

You can use one of the moment plugin -> moment-range to deal with date range:

var startDate = new Date(2013, 1, 12)
  , endDate   = new Date(2013, 1, 15)
  , date  = new Date(2013, 2, 15)
  , range = moment().range(startDate, endDate);

range.contains(date); // false

You can use

moment().isSameOrBefore(Moment|String|Number|Date|Array);
moment().isSameOrAfter(Moment|String|Number|Date|Array);

or

moment().isBetween(moment-like, moment-like);

I do believe that

if (startDate <= date && date <= endDate) {
  alert("Yay");
} else {
  alert("Nay! :("); 
}

works too...

Good news everyone, there's an isBetween function! Update your library ;)
