Salesforce Lightning:
Salesforce Lightning is a suite of tools and technologies designed to enhance and modernize the user experience on the Salesforce platform. It encompasses both the user interface and the underlying architecture that supports it. Salesforce Lightning includes:
1.Lightning Experience: This refers to the modern, responsive user interface that Salesforce users interact with. It replaced the older Classic UI and provides a more streamlined and visually appealing experience.
2.Lightning Components (Aura): Salesforce Lightning Components, often referred to as Aura components, are the building blocks of the Lightning Experience. They are reusable UI elements with their own JavaScript logic, CSS styles, and markup. Aura components were the first step towards modernizing Salesforce's UI development.
3.Lightning App Builder: This is a tool that allows administrators and developers to create custom pages and applications using Lightning Components. It provides a drag-and-drop interface to assemble components without writing code.
Lightning Web Components (LWC):
Lightning Web Components (LWC) is a more recent addition to the Salesforce Lightning platform. It's a modern UI framework designed to improve the development experience for building web components on the Salesforce platform. LWC represents a shift towards using standard web technologies, aligning with the Web Components standard. Key differences include:
1.Web Standards: LWC is built on standard web technologies like Web Components, which includes Custom Elements, Shadow DOM, and more. It moves away from the proprietary nature of Aura components and embraces open web standards.
2.Performance: LWC emphasizes performance optimization through native browser capabilities, reducing the reliance on complex frameworks.
3.Simpler Syntax: LWC simplifies the component syntax and reduces the boilerplate code needed for component creation.
4.Aura Compatibility: LWC and Aura components can coexist in the same application. This allows for gradual migration from Aura to LWC over time.
5.Modularity and Reusability: LWC promotes a modular approach to component development, enabling greater reusability and maintainability.
