How to Use Lightning Message Service (LMS) in Salesforce LWC
Summary
Lightning Message Service (LMS) in Salesforce allows Lightning Web Components, Aura components, and Visualforce pages to communicate seamlessly across the same Lightning page without needing a direct relationship or reference.

This enables components that are not parent or child to exchange data dynamically, facilitating modular and scalable app designs. The article walks through setting up LMS by creating a message channel, a publisher LWC, and a subscriber LWC, showing the practical steps for enabling inter-component communication.
