What is the best way to write this.

```auto

function myFunction(path, path2, path3, path4) {
     
      if (path != null) {
           f1._visible = true;
  ////then also turning on visibility on f2 for path 2, f3 for path3 ect.... only if they exist.
     like if (path2 != null) { ///was also not null then
           f2._visible = true; ////and so on only if they are present.

   
}

```

I have tried to write this many ways however nothing to avail. Can someone assist on this or point to some reading for crazy ifs
