# Salesforce Global Variables Blocked by Lightning Web Security

Lightning Web Security (LWS) blocks access to some global JavaScript objects that are available to other Salesforce features.

Lightning web components (LWC) **don’t have access** to:

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

LWS restricts access to these objects for Lightning web components because they are either deprecated or not supported for LWC.
