Bash treating variable expansion as command while passing to other script

Question

a=HDH b=udud c=jsjsj bash secondscript

The command above works. I'd like to save the assignments in a variable, like so:

value="\
    a=HDH \
    b=udud \
    c=ududj \
    "
$value bash secondscript

But it gives an error:

test.sh: line 9: a=HDH: command not found

Why? What can I do instead?

Ok so what should i do then ? Any workaround to achieve my goal — Golu

For an explanation of why you can't save assignments in a variable see my writeup here: stackoverflow.com/questions/61898254/…. — John Kugelman

bash's taking first item a=HDH as a command, what you need is :

value=(
  "a=HDH"
  "b=udud"
  "c=ududj"
)
env "${value[@]}" bash secondscript
