An example of an AI chatbot conversation about the purpose of IIFEs in JavaScript.
What is the purpose of IIFEs in JavaScript?
IIFEs, or Immediately Invoked Function Expressions, are used to create a new scope in JavaScript. They help avoid polluting the global scope.
Can you give me an example of an IIFE?
Sure! Here's a simple example: (function() { console.log('Hello, IIFE!'); })(); This function runs immediately after it's defined.
Why is it important to avoid polluting the global scope?
Avoiding pollution of the global scope helps prevent variable name conflicts and keeps your code modular and maintainable.
Are there any alternatives to using IIFEs?
Yes, you can use block scope with let and const in ES6, or modules to encapsulate your code without IIFEs.
