Tell us what’s happening:

cannot test/run code due to persistent message on console: “TypeError: Cannot read property ‘presets’ of undefined”

Your code so far


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

Maybe try pressing the “Reset All Code” button, refreshing your browser, then copying your solution back in.
