- Can a component outside of a provider get its context?
- No, you can’t. The only way to update context it would be change the value sent to the Context. Provider. React context is available only when the UI is available
- What are some common use cases for using the Context API?
- Theming — Pass down app theme.

With hundreds or thousands of employees, security is more easily maintained by limiting unnecessary access to sensitive information based on each user’s established role within the organization.
