(1) it's easier to learn a language that you can use interactively than
one that only works in some "file at a time" mode.
(2) it's often convenient to write a short script at the command line to
accomplish some one-off task. [If I'm doing a task a lot, I'll gradually
accrete a set of tools dedicated to that task. Early on they're purely
interactive commands, then short aliases and maybe small scripts, and
once I've formalized the work I might write a dedicated program or set
of programs for the task.]
There is no real distinction between interactive and non-interactive
work in the general case.
