I thought I grasped the concept of hoisting, but the code below got me confused. How does it return 1? Will the second example() function be hoisted above the first one?

function example() {
  return 9;
}

console.log(example());

function example() {
  return 1;
}

If a function declaration is hoisted in a compilation phase and a function expression is executed in the execution phase. How come the code below returns 7? Is it simply due to example expression being declared first?

var example = function() {
  return 7;
}

console.log(example());

function example() {
  return 0;
}

Thank you in advance!
