What does the Lightning Component framework provide to developers?

The Lightning Component framework does not inherently extend governor limits; applications built with it are still subject to the same Apex and platform governor limits.

The Lightning Component framework, encompassing both Aura and Lightning Web Components (LWC), offers a rich library of prebuilt, customizable components (e.g., UI components, form elements, data tables) that developers can readily reuse. This reusability significantly speeds up development and ensures consistency across applications within the Salesforce platform.

While developers can create custom components, the framework itself provides a syntax and structure for building them, rather than just 'templates' in the sense of predefined component structures; the core offering is the *ability* to build and a library of existing components.

The Lightning Component framework is designed primarily for the Lightning Experience UI; while some components may render in Classic, its main purpose and benefit are for modern Lightning UIs, not explicitly 'support for Classic and Lightning UIs' as an equal core offering.
