We really hope you've enjoyed our advent calendar. Please let us know on Twitter (#dotchristmas) if you did!

For our very last article in this advent calendar, we've made you a JavaScript-themed puzzle for when you're in need of a break from your beloved family members.

Head on over to Google Spreadsheets to make your own copy and start punching in those JavaScript keywords.

Have fun, and thanks for following along ❤️

See you next year!
