What are the differences between IIFE and arrow functions?
An example of an AI chatbot conversation about IIFE and arrow functions in JavaScript.
Can you explain the differences between IIFE and arrow functions?
Sure! An IIFE, or Immediately Invoked Function Expression, is a function that runs as soon as it is defined. Arrow functions, on the other hand, are a more concise way to write function expressions in JavaScript.
What are the main use cases for IIFE?
IIFEs are often used to create a private scope, avoiding polluting the global namespace. They're great for encapsulating code.
And what about arrow functions? When should I use them?
Arrow functions are ideal for writing shorter function expressions, especially when you need to preserve the context of 'this' from the surrounding code.
Can you give me an example of both?
Absolutely! An IIFE looks like this: (function() { console.log('I am an IIFE!'); })(); An arrow function example: const add = (a, b) => a + b;.
