Lightning web components are built using HTML and modern JavaScript and can coexist and interoperate on a page with the Aura components. They use core Web Components standards and as they are built to run natively in the browsers, they are lightweight and deliver exceptional performance.

The key to understanding the workings of the Salesforce Lightning Web Components is to learn how they communicate with each other. Communication is critical to write powerful, flexible, and dynamic Lightning Web Components. Moreover, their communication pattern varies from Auro components and that is why they deliver exceptional performance.
