SurveyJS
Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.
I'd consider using a library to help you out. Maybe something like https://date-fns.org, you could combine isBefore and isAfter to create a isInRange. Once you have that you can loop though your dateArr and for each entry, check if it's in any of your given ranges then increment the count.
