What happens when this code runs?

greet();
var greet = function () { console.log("hi"); };

✓Correct answer: TypeError: greet is not a function - only the var declaration is hoisted, as undefined
2It prints hi
3ReferenceError: greet is not defined

Explanation

Function declarations are hoisted with their body; function expressions follow the hoisting rules of the variable. With let or const you'd get a ReferenceError from the TDZ.
