Aura Component-based development is a framework for creating Lightning web components, which are the building blocks of modern Salesforce applications. Lightning web components are self-contained and reusable units of an application, which means they can be composed together to create complex user interfaces. They also benefit from a rich component ecosystem, which includes standard components provided by Salesforce, custom components created by developers, and third-party components available on AppExchange. These advantages make Aura Component-based development more flexible, modular, and efficient than Visualforce, which is an older framework based on HTML, JavaScript, and Apex. See Aura Components Basics1 and Lightning Web Components Basics2 for more details.
