What an insane math skills

U'r correct. They'r hoisted. It's working 'cuz code executed after your variable declaration. Yep, find same example)
Thanks for helping)

I can be wrong, reading a little more, if the const declaration were inside the function it won't work. I think it is a matter of scope. Check this

We can reference the let and const variables in the code (eg. function body ) even before they are declared, as long as that code is not executed before the variable declaration.

function foo () {
  console.log(a);
}
let a = 20;
foo();  // This is perfectly valid

Why I always thought it's not working for const and let only for var🤷 Thank you for fast answer

It's called hoisting

Why your variable work before declaration??? It's a bag or feature?
