In this blog, we will explore a powerful scenario. A Visualforce page dynamically loads an external JavaScript library. It defines a global method and passes it to a Lightning Web Component (LWC) using Lightning Out. The LWC can then invoke this method, optionally passing parameters, to generate dynamic responses. This use case demonstrates seamless interoperability…
