Skip to main content

Is it possible to end a script early? It seems like the process.exit() function isn’t available. I’d like to show an error message and exit if the input meets certain criteria.

I like to put the main functionality of a script inside a main function. If I want to end the script early, I use a return statement inside the script.


await main()

async function main() {

  // pseudo code for guard clause

  if (no data) {

    return;

  }

  // main script functionality

}

Almost all of my scripts have some sort of async call, so my main function almost always needs await/async. If your script doesn’t use any async calls, you can remove them.


This thread also has a discussion about using a “top-level” return, but it is not recommended.
