noRestrictedGlobals

Diagnostic Category: lint/style/noRestrictedGlobals

Since: v1.0.0 Sources:

This rule allows you to specify global variable names that you don’t want to use in your application.

References to the global identifiers error and event are always disallowed by this rule.

Disallowing usage of specific global variables can be useful if you want to allow a set of global variables by enabling an environment, but still want to disallow some of those.
