[SOLVED] Early return from a script (without a function)

Issue

I have multiple duplicated external scripts that I want to run just once.

I would like to return early on those scripts after the first time doing a small modification to those scripts, something like:

if (window.this_script_have_been_loaded) {
  something_like_return
}

// rest of script

window.this_script_have_been_loaded = true

But I do not want to add a big if or function around the existing code to make it easier to manage. Is there a return statement for scripts?

To prevent code from running, place this code inside a block statement and exit this block if needed with a break statement and a label.

label: {
    console.log('before');
    if (true) break label;
    console.log('after');
}
