# Restricted Access to Salesforce Global Variables

Lightning Locker blocks access to some global JavaScript objects that are available to other Salesforce features.

[Lightning web components (LWC)](/docs/platform/lwc/guide/get-started-introduction.html) **don't have access** to:

- `$A`
- `Aura`
- `Sfdc`
- `sforce`

Locker restricts access to these objects for Lightning web components because they are either deprecated or can lead to cross-framework dependencies.
