JavaScript (Velo by Wix)

Custom JS to extend Wix functionality.

Velo enables JavaScript on Wix to build custom UI behavior, form logic, and API integrations. You can validate fields, create dynamic filtering experiences, control member flows, and build custom dashboards. For maintainability, keep scripts modular, avoid hardcoding IDs without documentation, and use backend modules for sensitive operations. JavaScript is the bridge between no-code speed and real product-grade functionality.
