AI translates the explanation and quiz text while preserving code and answer scoring.

Lightning Web Components (LWC) are built using standard Custom Elements, Shadow DOM, and modern JavaScript. LWC communicates with Apex controllers using `@wire` reactive adapters or imperative Apex method calls.

javascript
import { LightningElement, wire } from 'lwc';
import getAccounts from '@salesforce/apex/AccountController.getAccounts';

export default class AccountList extends LightningElement {
    @wire(getAccounts) accounts;
}
