Script Granny
Trivia
The Javascript console model has the Japanese katakana characters "クッキークリッカー ジャバスクリプト" (Kukkii Kurikkaa Jabasukuriputo) which translate to "Cookie Clicker JavaScript".
Before version 2.028, the Javascript console model is miswritten as "クツキークリツカー ジャバスクリプト" (Kutsukii Kuritsukaa Jabasukuriputo).
This is the second building to have a completely different store icon compared to its appearance in the buildings overview, after the Time Machine.
Unlike all other buildings, the Javascript console's grandma appearance is dependent on the Script grannies synergy upgrade, rather than the Binary grandmas type upgrade.
The Achievement "F12" refers to the F12 key opening the browser console.
The Achievement "No Comments" is a reference to comments that are written in code to help explain what certain lines of code are doing.
The Upgrade "Stack overflow" is a reference to a stack overflow, or to the Q&A site for programmers.
The Upgrade "Cookies++" is a reference to the C++ programming language and the fact that the "++" operator increases a variable by one.
The flavor text for the upgrade "A Nice Cup of Coffee" is a reference to the fact that java is a name for coffee and that Java is a programming language that many people confuse with JavaScript.
The flavor text for the upgrade "The JavaScript console for dummies" is a reference to the series of informative books of a similar name.
The "Alexandria" achievement may be a reference to the Library of Alexandria and coding libraries.
