It takes an `other` object as an argument and returns a Boolean value. For example, if `dateRange1` is '2017-06-24' to '2017-07-24' and `dateRange2` is '2017-06-30' to '2017-07-10', `dateRange1.contains(dateRange2)` will return `true`. Otherwise it will return `false`. The method is used in both JavaScript and Python.\n"]]
