Another underlying principle worth mentioning here for the example starting at 3:05 is called "variable shadowing". Because our inner variable's name is the same as the outer variable's, a variable in the inner scope is said to shadow a variable in the outer scope. That is why we cannot re-assign a value assigned to a global variable.
However, if you tweak this example a little bit:

let number = 10;
function increase() {

number++;
}

increase();
console.log(number);

So, here we are not passing in any arguments and therefore a value in the global variable can be re-assigned.
