ES6 - Compare Scopes of the var and let Keywords

Tell us what’s happening:
Describe your issue in detail here.

checkScope() should return the string function scope. I do not understand how I get it return that.

Your code so far

function checkScope() {
  let i = 'function scope';
  if (true) {
    i = 'block scope';
    console.log('Block scope i is: ', i);
  }
  console.log('Function scope i is: ', i);
  return i;
}

function checkScope() {

You are declaring i with function scope. The problem is that when you run i = 'block scope';, it is referring to that same variable. You need to declare a second variable i that only refers to that block scope so that the function scope i does not change.

Does that make sense?
