How to loop through file names returned by find?

Question

x=$(find . -name \"*.txt\")
echo $x

if I run the above piece of code in Bash shell, what I get is a string containing several file names separated

Answer 1

based on other answers and comment of @phk, using fd #3:
(which still allows to use stdin inside the loop)

while IFS= read -r f <&3; do
    echo "$f"

done 3< <(find . -iname "*filename*")
