invalid_with_sideeffect_import.js:3:1 lint/complexity/noUselessEmptyExport  FIXABLE  ━━━━━━━━━━━━━━━

  ! This empty export is useless because there's another export or import.
  
    1 │ import "mod"
    2 │ function f() { return 0 }
  > 3 │ export {}
      │ ^^^^^^^^^
  
  i This import makes useless the empty export.
  
  > 1 │ import "mod"
      │ ^^^^^^
    2 │ function f() { return 0 }
    3 │ export {}
  
  i Safe fix: Remove this useless empty export.
  
    1 1 │   import "mod"
    2 2 │   function f() { return 0 }
    3   │ - export·{}
