What Can You Return From A JavaScript IIFE? Ever wondered what a JavaScript Immediately Invoked Function Expression (IIFE) can give back to your code? In this detailed video, we'll explore the different types of values that an IIFE can return. We’ll explain how IIFEs work as a quick way to execute functions immediately and how their return values can be anything JavaScript understands. You’ll learn about primitive data types like numbers, strings, and booleans, as well as more complex data structures such as objects and arrays. We’ll also cover how returning functions from an IIFE is useful for creating closures, private variables, and encapsulated modules. If you don’t include a return statement, the IIFE will return undefined, which is helpful when you only want to run some code without storing a value. Additionally, we’ll show how you can assign an IIFE’s return value to a variable to set up configuration data or internal states. Understanding what an IIFE can return helps you write more organized and controlled code, especially for managing private data and creating modular scripts. Whether you’re working on small scripts or complex applications, mastering IIFEs and their return values is a key skill for web developers.
