Can you access variables defined inside an IIFE from outside the function?
(function() {
var privateVar = 'I am private';
})();
console.log(privateVar);
No, variables defined inside an IIFE are not accessible from outside the function. In the given code, trying to access 'privateVar' outside the IIFE will result in a ReferenceError because 'privateVar' is scoped to the IIFE. This encapsulation is one of the main benefits of using IIFEs - they create a private scope that prevents variables from leaking into the global scope. This helps avoid variable name collisions and keeps the global namespace clean. If you need to access values from an IIFE, you would need to explicitly return them or assign them to variables outside the IIFE.
