Description

I am trying to do a multiple function filters for an angular project following this code:

https://codepen.io/anon/pen/MMaRyB?editors=1011

but i am having trouble at line 36 with .is function (ERROR TypeError: i.is is not a function) I am guessing its jquery function. Is there any equal on vanilla / typescript to replace it?

Research direction
Examine Isotope's filter implementation to understand where the jQuery .is function is used. Replace it with native Element.matches() or a similar vanilla JavaScript/TypeScript alternative. Consider creating an Angular directive or service to wrap Isotope functionality without jQuery. Check the issue comments and repository for any existing work or discussions on removing jQuery dependencies.
