Maintaining codes without structured information

As a reader, I guess I can understand why some of the logic are flawed.

I really want to express the appreciation to Lua Language Server. It brings the possibility to document and track a table object so that after a while of passing it around, I can still know what the current variable is (there are TABLES everywhere!) I would say that the annotation is the shinning light tower, as the Beledar, in this dark, endless pit.

Without our Beledar to keep track the information of my code, I could definitely make similar, maybe more errors.
