Is this code wrong? I don't get the result

Tell us what’s happening:

function myLocalScope() {
   'use strict';

  // Only change code below this line
   var myVay;
  console.log('inside myLocalScope', myVar);
}
myLocalScope();

// Run and check the console
// myVar is not defined outside of myLocalScope
console.log('outside myLocalScope', myVar);

Your code so far


function myLocalScope() {
 'use strict';

// Only change code below this line
 var myVay;
console.log('inside myLocalScope', myVar);
}
myLocalScope();

// Run and check the console
// myVar is not defined outside of myLocalScope
console.log('outside myLocalScope', myVar);

Instead of var you should use let because they only want to be used inside the function not outside.

For the purpose of this challenge, var works as well.

I am not a fan of using var, but it is function scoped so it works. let is block scoped.
