Your code always need to be console.log('STRING'); Always use same pair of ' ' or " " or it won't work. If you'r string contain a ' like this one : John's house, you'll need to type it this way : "John's House" or 'John\'s House'.

Work well and happy coding!

You can use either double quotes or single quotes, but you can't start the string with a single quote and end it with a double quote. Examples:

"Hello"  // This string is valid
'Hello'  // This string is valid
"Hello'  // This string is invalid
'Hello"  // This string is invalid
