How to avoid a large number of arguments in functions?

Question

go

In general, I wrote a program, and then it was necessary to introduce several additional features, due to which instead of 2-3 arguments there are now 5 arguments in functions. in so many arguments?

Answer 1

Ideally, redo.
If it is not possible to remake, the structures will definitely be better.
There is also a "functional options" option https://golang-blog.blogspot.com/2019/10/functiona...

Answer 2

Use functional options with prescribed default values

Or wrap optional fields in a structure and pass the structure as a function parameter.
If it is possible to remake a function so that it requires fewer arguments, then it is better to do so, for example, split it into 2 functions, if one depends on the other and because of this you have to pass more parameters than necessary.
