@sencha/extjs/no-private-property-usage

Report the usage of a private property

Rule Details

This rule will report when a private property is being used.

In this example, the complete property is a private property of the Ext.data.Batch Class that was introduced in version 5 and is still a private property as of the latest version. Therefore, this problem will only be reported if the fromVersion in the extjs settings is set to >= 5 and the toVersion is also set to >= 5.
