Who will help


who can explain the problem:

this javascript:

// Declare a variable on line 3 called
// myCountry and give it a string value.

var myCountry;

// Use console.log to print out the length of the variable myCountry.


// Use console.log to print out the first three letters of myCountry.

Should be:


And the same with the substring.
You also never gave the myCountry variable a value.
For example:

myCountry = "United States"


Thank you the code works
