# What is Lightning Web Components?

> Lightning Web Components (LWC) is Salesforce's framework for building custom user interface components with standard web technologies. Each component is a bundle of files, typically JavaScript, HTML and metadata, and can call Apex and be placed on pages with Lightning App Builder.

Also called: LWC.

## Why it matters

Components are code, so they need the same care as Apex: their Apex calls, the properties admins can set and the pages they appear on all have to stay consistent.

## In SyncOnAI 360

SyncOnAI 360 syncs every file of each component, provides a visual builder with a library of more than 700 components generated from Salesforce's own source, wires Apex calls on both sides together, and proposes a component with its controller and test as one change.
