  6. arr.drop(n) Return An Array, Or List, With The First N Elements Removed

  7. arr.drop(n) • Explicitly returns an Array, or List, with n elements removed from the front.

  8. arr.init Return An Array, Or List, With The Last Element Removed

  9. arr.init • Explicitly returns an Array, or List, with n elements removed from the rear.

  10. arr.head & arr.first Return The First Element Of The Array Or List

  11. arr.head & arr.first • Explicitly returns the first element in the Array or List.

  12. arr.last Return The Last Element Of The Array Or List

  13. arr.last • Explicitly return the Last Element in the Array or List.

  14. arr.slice(f,l) Return The Array, or List, Beginning With Element f & Continuing To The Element Just Before l

  15. arr.slice(f,l) • Explicitly returns an Array, or List, Beginning With Element f & Continuing To The Element Just Before Element l.

  21. arr.takeRight(n) • Explicitly Return The Array, or List, Of n Elements Taken From The End/Right • .

  22. arr.contains(n) Return true If n Is In The List Or Array

  23. arr.contains(n) • Explicitly Return trueIf n Is One Of The Data Element Members Of The List Or Array; Otherwise Return false • .

  24. arr.isEmpty Return true If The Array, Or List, Is Empty – Has 0 Data Element Members

  25. arr.isEmpty • Explicitly Return trueReturn true If The Array, Or List, Is Empty – Has 0 Data Element Members; Otherwise Return false • .

  26. arr.nonEmpty Return true If The Array, Or List, Is Empty – Has 0 Data Element Members

  30. arr.indexOf(n) Return The Element Subscript If The n Is A Member Of The Array, or List; Return -1 If The Element Is Not In The Array Or List

  31. arr.indexOf(n) • Explicitly Return The Element Subscript If The n Is A Member Of The Array; Return -1If The Element Is Not In The Array.

  32. arr.lastIndexOf(n) Return The Element Subscript If The n Is A Member Of The Array, Or List; Return -1 If The Element Is Not In The Array Or List

  33. arr.lastIndexOf(n) • Explicitly Return The Element Subscript If The n Is A Member Of The Array; Return -1 If The Element Is Not In The Array.

  34. arr.diff(arr1) Return An Array, Or List, Containing Those Elements In arr1, That Are Not In arr.
