After recently updating my local J-Query library from 1.9.1 to 3.6.0 I have noticed some strange issues. I did not see anything online for this, and most of these functions are standard JavaScript functions I believe, and not J-Query. I am seeing that Date() objects are undefined. Also the following errors with Date and Array objects are happening. If I revert the code to 1.9.1 there is no issue. *Also this is a Node.js project, I dont know if that matters.

TypeError: Date.today is not a function at Object. (main.js:8:126614)

Cannot read properties of undefined (reading 'includes')

TypeError: i.add is not a function

Sample Code

        var today = Date.today();

UPDATE: It looks like the code that is not working is coming from this node.js package.

https://github.com/datejs/Datejs

When I change the code to

var today = new Date();
var numberOfDays = today.add(5).days();

Then there is a problem with the add method, see the error listed above.
