Function Level Code Smells | Clean Coding | Dumb Minds

In computer programming, a code smell is any characteristic in the source code of a program that possibly indicates a deeper problem.Determining what is and is not a code smell is subjective, and varies by language, developer, and development methodology.

Too many parameters: a long list of parameters is hard to read, and makes calling and testing the function complicated. It may indicate that the purpose of the function is ill-conceived and that the code should be refactored so responsibility is assigned in a more clean-cut way.
Long method: a method, function, or procedure that has grown too large.
Excessively long identifiers: in particular, the use of naming conventions to provide disambiguation that should be implicit in the software architecture.
Excessively short identifiers: the name of a variable should reflect its function unless the function is obvious.
Excessive return of data: a function or method that returns more than what each of its callers needs.
Excessive comments: a class, function or method has irrelevant or trivial comments. A comment on an attribute setter/getter is a good example.
Excessively long line of code (or God Line): A line of code which is too long, making the code difficult to read, understand, debug, refactor, or even identify possibilities of software reuse.
