Aura Components in Salesforce provides businesses with several benefits including efficient data binding, client-side caching, and a powerful event model. Additionally, Aura Components are easy to develop and maintain and are designed to work across all devices and platforms.
Lightning Web Components offer enhanced performance, modular structure, and seamless integration with Salesforce. They allow for fast and responsive user experiences through techniques such as lazy loading and efficient data retrieval. Additionally, they are interoperable with other frameworks, such as Shadow DOM and Custom Elements, which ensure compatibility.
Yes, you can use LWC and Aura Components side by side, but Aura is the ultimate parent. An Aura Parent can contain both LWC and Aura components, but an LWC parent can only contain LWC components.
By leveraging the interoperability between Aura Components and Lightning Web Components, you can migrate from Aura Components to LWC gradually. This allows you to start using the new features of LWC while still leveraging the existing Aura components. You can also use the Lightning Web Components migration tool to help you migrate your Aura components into LWCs.
