Why you should care

[/vc_column_text][vc_column_text]There is no reason to re-assign a variable to itself. Either this statement is redundant and should be removed, or the re-assignment is a mistake and some other value or variable was intended for the assignment instead.[/vc_column_text][vc_empty_space][/vc_column_inner][/vc_row_inner][vc_empty_space height=”12px”][vc_empty_space][vc_separator][vc_column_text]

How we detect

[/vc_column_text][vc_column_text]This Code Insight counts one occurrence each time a variable is re-assigned to itself.

Bad Code

func (user *User) rename(name string) {
name = name // Noncompliant
}

Good Code 

func (user *User) rename(name string) {
user.name = name
}
