Lightning Web Components framework doesn’t have dependencies on the Salesforce platform. Instead, Salesforce-specific services are built on top of the framework. What that layered architecture means is that you can now use the Lightning Web Components framework to build web apps that run anywhere.

In the past, developers often had to use different frameworks to build different sides of an application. For example, you’d use Aura to build the employee-facing side of an application on Salesforce and React, Angular or Vue to build the customer engagement side of the application on Heroku or any other platform. Today, you can use Lightning Web Components to build both sides of the application. The benefits are significant: you only need to learn a single framework and you can share code between apps. And because Lightning Web Components is built on the latest web standards, you know you are using a cutting-edge framework based on the latest patterns and best practices.
