In order to optimize performance and reduce memory usage, ExtJS (along with other JavaScript frameworks) utilizes private classes to encapsulate objects that are only used internally. These classes are named intelligibly within the source code.
However, in the release version of the framework, minification is applied for better efficiency. When a class or member is marked as private, its name can be reduced to a single letter during minification. This may result in some objects having unusual names when inspected by debugging tools.
Therefore, the seemingly strange names you are seeing are not console anomalies but rather the result of the minification process employed when releasing the JavaScript framework.
