Salesforce is a leading cloud platform for building enterprise applications and managing customer relationships. With the introduction of Lightning Web Components (LWC), developers now have a fast, modern way to create dynamic user interfaces in Salesforce. To speed up development and simplify testing, online tools and resource hubs provide essential support throughout the entire coding process. In plain words: LWC online tools and playgrounds let Salesforce developers quickly generate boilerplate code, test UI components in real-time browser sandboxes, and access reusable code recipes without waiting for full local environment deployments.
