In this lesson, you'll learn about some of the more advanced and tricky concepts in JavaScript: , , and . These are important topics, especially for understanding how JavaScript works under the hood and for technical interviews.

Overview of Upcoming Lessons

In the upcoming three lessons, we're going to cover some tricky concepts in JavaScript: , , and .

1. : We'll start with the concept of scope, which is fundamental to any programming language. Scope determines the accessibility of variables and functions in different parts of your code.
2. : Next, we'll discuss hoisting, a JavaScript-specific behavior that affects variable and function declarations. While hoisting might not be something you use consciously in everyday coding, understanding it can help you avoid potential pitfalls.
3. : Finally, we'll explore closures, a powerful feature in JavaScript that allows functions to retain access to their lexical scope even when executed outside of it. Closures are often considered tricky but are incredibly useful once you understand them.

While these concepts might not be part of your daily coding routine, they are important to know, especially since questions about closures and hoisting often come up in technical interviews. I've got you covered! 😉

As we dive into each topic, you'll gain a deeper understanding of how JavaScript works and be better prepared for any questions that come your way. Let's get started!
