var isn't global unless it's not inside a function. var is just function scoped, with declaration auto hoisted to the beginning of the function. let is a little more intuitive since you can't refer to it before it's been declared and has block scope rather than function scope.

Wait...... you can use a variable before you declare it?

var a;
(function() {
  a='hoisted';
  console.log(a);
  var a;
})()
console.log(a);

Should log hoisted and then undefined, showing that you've assigned to the later-declared var a which was hoisted vs the external global a.
