I think you need to introduce console.log before you start using it in the examples. Maybe add an intro chapter before we get into strings, numbers and Booleans? The intro chapter would say (1) JavaScript is the language of the web. (2) Here's how you can use JavaScript in your browser (open the console). We can "print" the results of any operation using the console.log() function. (3) Now it's time to learn how JavaScript works, starting with the types of data found in JavaScript. First up: Strings, Numbers, and Booleans.
