-1 and str.length-1 are same in slice method but beginners get confused what -1 does here ? To avoid the confusion I used str.length-1 in both examples.
-1
str.length-1
I'd love to see the method mentioned by Jon as a bonus method, with explanation as to what the -1 does so beginners can understand
