What is @tootallnate/once?

What are @tootallnate/once's main functionalities?

Ensuring a function is only called once

This feature allows you to wrap any function with `once` to ensure it can only be executed a single time. Subsequent calls to the wrapped function will have no effect, preventing duplicate execution.

const once = require('@tootallnate/once');

function myFunction() {
  console.log('This will only be logged once.');
}

const wrappedFunction = once(myFunction);
wrappedFunction(); // Logs: 'This will only be logged once.'
wrappedFunction(); // Does nothing on subsequent calls.
