zsh makes this so much easier. This doesn't capture $i, but covers most use cases of "I want to run something more than once":

  repeat 10; echo "repeat me"

If you do need $i you can use a similar construct as bash, but more convenient:

  for ((i = 0; i < 10; i++)); echo $i

  for i in {0..10}; echo $i  # {n..m} loops also work in bash

  for ((i = 0; i < 10; i++)); { echo $i; echo $i }  # Multiple commands

Short loops are hugely helpful in interactive use because it's much less muckery for short one-liners (whether you should use them in scripts is probably a bit more controversial).

Also looping over arrays "just works" as you would expect without requiring special incantations:

  arr=(a b)
  for v in $arr; echo $v

Whether zsh or fish is better is a matter of taste, and arguably zsh has too many features, but IMHO bash is absolutely stuck as a "1989 ksh clone" (in more ways than one; it uses K&R C all over the place, still has asm hacks to make it run on 1980s versions of Xenix, and things like that).
