You just had to declare the variable (var) called myVar in a local way (it means, inside a function) like this:
function myLocalScope() {
'use strict';
// Only change code below this line
var myVar;
console.log('inside myLocalScope', myVar);
}
myLocalScope();
// Run and check the console
// myVar is not defined outside of myLocalScope
console.log('outside myLocalScope', myVar);
Declare a variable can be just write it empty, like i do.
Follow the directions closely. It’s telling you to only change code below that line. Don’t change anything else. An important part of being a good developer is following directions very closely, paying attention to minute details.
