invalidFunction.cjs:3:2 lint/suspicious/noRedundantUseStrict  FIXABLE  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

  ! Redundant use strict directive.
  
    1 │ function test() {
    2 │ 	"use strict";
  > 3 │ 	"use strict";
      │ 	^^^^^^^^^^^^^
    4 │ }
    5 │ 
  
  i This outer use strict directive already enables strict mode.
  
    1 │ function test() {
  > 2 │ 	"use strict";
      │ 	^^^^^^^^^^^^^
    3 │ 	"use strict";
    4 │ }
  
  i Safe fix: Remove the redundant use strict directive.
  
    1 1 │   function test() {
    2 2 │   	"use strict";
    3   │ - → "use·strict";
    4   │ - }
      3 │ + → }
    5 4 │
