Walkthrough

The pull request refactors the checkRequiredField function in js/formidable.js by replacing jQuery-based DOM querying with vanilla JavaScript. Specifically, it substitutes the use of jQuery’s element selection and looping with document.querySelectorAll and a forEach iteration over input elements. The refactoring maintains the function’s error handling and value extraction logic while eliminating an unnecessary variable (checkGroup).
