Question 1

Is Lightning Web Components faster than React?

Accepted Answer

Yes, LWC is optimized for performance with a compiled component model that often outperforms React in benchmarks due to minimal runtime overhead. However, React offers a larger ecosystem and more flexible state management for diverse use cases.

Question 2

How to use LWC outside of Salesforce?

Accepted Answer

LWC can be used independently by setting up the compiler and tooling as per the LWC.dev guide, but configuration might require extra steps, and some features are tailored for Salesforce integration. Start with the standalone documentation for best practices.

Question 3

LWC vs Stencil for building web components?

Accepted Answer

LWC excels in performance and enterprise scale with a compiler-driven approach, ideal for Salesforce-heavy projects. Stencil is more framework-agnostic and flexible, better for teams wanting broader ecosystem compatibility without vendor ties.

Question 4

What are the main drawbacks of adopting LWC?

Accepted Answer

Key drawbacks include dependency on the LWC compiler for builds, limited third-party library support compared to larger frameworks, and a steeper learning curve for developers unfamiliar with Salesforce conventions or web standards.

Question 5

How to test LWC components effectively?

Accepted Answer

LWC provides comprehensive testing with unit, integration, and performance workflows, as indicated by the test badges in the README. Use the built-in testing tools and follow the documentation for reliable, scalable component validation.

Question 6

Can I integrate LWC with an existing Angular project?

Accepted Answer

Yes, since LWC uses standard web components, you can embed them in Angular apps, but may need polyfills or additional configuration for full compatibility. Check the LWC interoperability guides for specific integration steps.

Question 7

Is LWC good for building mobile web apps?

Accepted Answer

LWC is web-based and can be used for mobile web applications, but it's not specifically optimized for native mobile performance. For hybrid apps, consider pairing with frameworks like Ionic, though testing on mobile devices is recommended.
