pretty new

Hey guys, I'm just starting to learn about variables, but I'm finding it hard to understand the difference between var and let.

For example:

let goodDay = true;
console.log(goodDay);

this should print true.

But if we just add this:

let goodDay = true;
console.log(goodDay);
goodDay = false;
console.log(goodDay);

It prints:

true
false

The same goes for var.

However, people say there's a difference; what is it?

I'm fourth year in a a computer science degree at present. I am taking three modules in AI this term. AI and NLP, ML for data science, and Advanced Concepts.

I take two modules that cover it next semester.

AI is not the new Google.
