What is the difference between Salesforce Lightning and LWC?

Salesforce Lightning and LWC: In the ever-evolving landscape of customer relationship management (CRM) systems, Salesforce remains a trailblazer. With its powerful suite of tools, Salesforce empowers businesses to streamline their processes and enhance customer interactions. Two prominent components within the Salesforce ecosystem that often raise questions among users are Salesforce Lightning and Lightning Web Components (LWC). In this blog post, we’ll delve into the intricacies of these technologies, exploring their differences, similarities, and use cases.

Salesforce Lightning Overview:

Salesforce Lightning is a comprehensive framework designed to offer a more dynamic and responsive user experience within the Salesforce environment. Introduced in 2015, Lightning replaced the classic Salesforce user interface, bringing a modern, component-based architecture to the forefront. This framework comprises various tools and services, including Lightning Components, App Builder, and more, enabling users to build intuitive, customizable interfaces for their Salesforce applications.

Key Features of Salesforce Lightning:

  1. Lightning Components: These are reusable building blocks that facilitate the creation of dynamic and interactive user interfaces. Developers can use pre-built components or create custom ones to meet specific business requirements.
  2. App Builder: An intuitive drag-and-drop interface that allows users to design and customize the layout of their Salesforce applications. It simplifies the process of creating pages with Lightning Components.
  3. Lightning Experience: The Lightning Experience is the modern user interface for Salesforce, providing a more visually appealing and user-friendly environment compared to the classic UI.
