## What it is
Lightning Web Components (LWC) is an open-source UI framework from Salesforce for building fast, standards-based web components and apps using HTML, modern JavaScript, and CSS. It includes the LWC engine and compiler, and can be used both to customize Salesforce and to build standalone web applications.

## Use cases
- build web apps with standards-based web components
- create custom elements using html and modern javascript
- develop lightning web components for the salesforce platform
- scaffold a single page app with lwr
- build enterprise-grade ui components with minimal boilerplate
- learn web components with an online playground

## When to choose
- you want a lightweight, standards-based web components framework
- you are developing on or integrating with the Salesforce platform
- you need an enterprise-grade, performance-optimized component engine
- your team prefers plain HTML, ES6+ JavaScript, and CSS over heavy abstractions

## When to avoid
- you need a full-featured SPA framework with routing and state management built in
- you must support very old browsers beyond IE 11
- you prefer ecosystems like React or Vue with larger communities and libraries
- you need features available only on the Salesforce platform rather than open source
