This is what i wrote. I'll put the words in bold that i used:
// Declare a variable on line 3 called
// myCountry and give it a string value.
var myCountry: United Kingdom
// Use console.log to print out the length of the variable myCountry.
// Use console.log to print out the first three letters of myCountry.
Editor: Oops, try again. There was a problem with your syntax.
Syntax: SyntaxError: Unexpected token :
Where is that colon? Please tell me a solution.
