Hey there, coders! Let's decode this JavaScript snippet!

🔍 Explanation:
1️⃣ Inside the function sayHi(), we're trying to log the values of name and age to the console.

2️⃣ However, JavaScript has something called "hoisting", which means variable declarations are moved to the top of their scope. So, even though name and age are declared inside the function, their actual assignments come later in the function.

3️⃣ When we try to log name and age before their declarations, name gets hoisted but is undefined at that point. For age, since it's declared with let, it's in a "temporal dead zone" and accessing it before the declaration results in a ReferenceError.

4️⃣ Therefore, when we run sayHi(), it logs undefined for name and throws a ReferenceError for age.
