What is @tootallnate/once?
The @tootallnate/once package is designed to ensure a given function can only be called once. It is particularly useful in scenarios where you want to prevent duplicate execution of event handlers or other functions that should only run a single time during the lifecycle of an application.
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.

lodash.once
Part of the Lodash library, lodash.once provides a utility function to ensure a given function can only be called once.
