Ending while loop using if

Question

Is there a way to end a while loop by using an if? Here's just some pseudocode of the basics of what I want to do:

re = 1
while [re = 1]
do
    echo "hello, enter name"
    read name
    echo name
    echo "continue? 1 for yes, 0 for no"
    read re
    if [re == 1]
    then
        pass
    elif [re == 0]
    then
        end while
    else
        pass

It looks like you need to use continue in place of pass if you want to skip the rest of the loop and start again from the beginning, and you need to use break instead of end while if you want to exit the loop altogether.

Yes, bash supports the break command to do that:

 i=0; 
 while [ $i -lt 10 ]; do 
    if [ $i -eq 3 ]; then 
       break 
    fi
    echo $i
    let i++
 done

Will output:

 0
 1
