Are variables declared with let or const hoisted?

Question

I have been playing with ES6 for a while and I noticed that while variables declared with var are hoisted as expected...

console.log(typeof name         


        

Answer 1

From MDN web docs:

In ECMAScript 2015, let and const are hoisted but not initialized. Referencing the variable in the block before the variable declaration results in a ReferenceError because the variable is in a "temporal dead zone" from the start of the block until the declaration is processed.

console.log(x); // ReferenceError
let x = 3;
