Are there security restrictions on using modern JavaScript features like async/await in Lightning components?
Recommended Answer Update
Lightning Web Components (LWC) don't have security restrictions on using modern JavaScript features like async/await. Security is managed by Salesforce's Lightning Web Security (LWS), which provides a secure JavaScript sandbox. LWS ensures security not by restricting standard features, but by isolating components and preventing unsafe direct access to globals or DOM, while ensuring safe server-side calls through Apex.
Reasoning
The original answer had clarity issues due to run-on sentence structure and awkward phrasing that made it difficult to parse. The recommended update improves readability by breaking the long sentence into clearer, more digestible parts while preserving all the original technical information. No content was outdated or incorrect - the explanation of LWS providing security through isolation rather than feature restriction is accurate. The security rules selected relate to Lightning component security: AvoidAuraWithLockerDisabled addresses older Aura component security (Locker Service) which provides helpful context about Salesforce's evolution to LWS for Lightning Web Components, and @lwc/lwc/no-inner-html relates to LWC-specific security practices that complement the secure sandbox environment described in the FAQ.
