javascript hoisting arrow-functions JavaScript

I've tried everything I can think of but I've tried everything I can think of but I'm refactoring my project and I'm working on a personal project and I'm working with a perplexing behavior related to function hoisting in JavaScript when using arrow functions... I have a simple script where I'm trying to call an arrow function before its definition, and I expected it to behave like a regular function declaration. Instead, I'm getting a `TypeError: myFunction is not a function`. Here's a minimal example: ```javascript console.log(myFunction()); // TypeError: myFunction is not a function const myFunction = () => { return 'Hello, World!'; }; ``` I understand that regular function declarations are hoisted, allowing them to be invoked before their definition, but it seems that arrow functions are treated differently. I've tried moving the function definition above the call and it works fine, but I want to understand why this is the case. Is this an expected behavior according to the JavaScript specification? Also, are there any best practices I should consider when working with arrow functions in this context? Any insights would be appreciated! I recently upgraded to Javascript 3.11. I've been using Javascript for about a year now. Thanks for any help you can provide!
