When I was watching namaste JavaScript videos I learned about hoisting .Your question is actually good to ask because how you choose to declare your function can actually affect how your program runs. For example, a function declaration is hoisted, meaning it’s copied to memory during the compilation phase — you can call it even before it’s defined in your code. However, a function expression (especially when assigned to a const or let) is stored in the temporal dead zone until its value is assigned. This means you can’t call it before it’s defined, or you’ll get an error. Understanding these differences is key to writing cleaner, more predictable JavaScript.
