How to prevent refresh after form submits?

[teal pike]

I have a blade form

<form method="POST" action="{{ route('blah-path') }}">
    <input type="text" name="blah" />
    @csrf
    <input type="submit" value="Send" />
</form>

In the corresponding controller function, it have no return statement.

But I noticed, at the end of every submit, the page refreshes. How can you stop it from refreshing?

There was a name for this type of questions.

What are you trying to accomplish, and why is there no return on the method that processes that form?
