That way, we will get 3 unique moment objects and their respective datetime values.įor backend applications, it is pretty common to validate that the properties found in the request body are the specified type that we expect them to be. const today = moment()Ĭonst oneWeekLater = today.clone().add( 1, "week")Ĭonst twoWeeksLater = today.clone().add( 2, "week") Hence, the solution to this problem is rather straight forward - we simply have to clone the moment object before performing arithmetic operations. add, moment mutates the original object rather than mutating a copy of that object. This is because it turns out that all 3 constants refer to the same moment object, with the same datetime value. However, when we log the 3 values, it turns out that they all have the same date.

const today = moment()Ĭonst oneWeekLater = today.add( 1, "week")Ĭonst twoWeeksLater = today.add( 2, "week") Instead of constantly writing hard coded values like “”, “”, I could create relative moment objects for testing.

And for those who don’t have to, this article also serves as an interesting read for those who are curious about problems that can come from Moment.js & working with DateTime.
