Is there a better way to run a command N times in bash?

Question

I occasionally run a bash command line like this:

n=0; while [[ $n -lt 10 ]]; do some_command; n=$((n+1)); done

To run some_command

Answer 1

Using a constant:

for ((n=0;n<10;n++)); do some_command; done

Using a variable (can include math expressions):

x=10; for ((n=0; n < (x / 2); n++)); do some_command; done
