Methods in components could be organized using comments. Common usecases can be broken down into the following comment headers.
The name of a variable or function should tell you what it is and how it is used.
Comments can lie. They can be wrong to begin with, or they can be originally accurate and then become outdated over time as the related code changes.
Comments can often be avoided by using clearly named variables and extracting sections of code into clearly named functions.
Comments that describe what a method does, what arguments it takes, and what it returns are often redundant at best and misleading at worst.
