Laravel Frontend JavaScript Error Fix

I have a production-level Laravel application whose user interface has started throwing JavaScript errors. Those errors now break three critical areas:
• forms and any data-entry validation
• page navigation and routing handled client-side
• interactive components such as sliders, modals and similar UI widgets

My goal is to eliminate those errors and, while you are in the code, update any outdated front-end assets so the experience is smooth on all modern browsers.

The stack is standard Laravel with Blade views and vanilla JavaScript; no major framework like Vue or React was intentionally added, so the fixes should stay within that scope. You will receive access to a git branch containing the current code along with specific pages where the console is reporting issues.

Acceptance criteria
• No uncaught JavaScript errors in browser dev-tools on the affected pages
• Forms submit and validate correctly (both client-side and server-side hooks)
• Navigation links and route-based redirects work without manual page refreshes
• All interactive elements open, close and animate as originally designed
• Code changes committed back through a pull request with concise comments

If you are comfortable debugging Laravel-Blade templates, jQuery or vanilla JS, I’m ready to grant repo access right away so we can get this resolved quickly.
