As you build more complex apps, Discord bots, and websites you may want to optimize your code. If you have a function that you repeat across multiple files in your app you may consider creating a helper file where that function can live but also be available for use across your app. The benefits of doing this are that you will not have to repeat yourself, your code will be cleaner and easier to follow. When you make a change to a function in a helper file, the code will update everywhere in your app and in this way makes it easier to maintain the app!
