Yes. Introduction to Computer Science in JavaScript (Corgi) is the CodeHS flagship intro course, built to start from zero. Students begin by giving simple commands to Karel the Dog, then move into writing real JavaScript. It covers material equivalent to a one-semester college introductory CS course, making it a solid foundation for any student new to programming.
No. Introduction to Computer Science in JavaScript (Corgi) assumes no prior coding experience. It opens with Karel the Dog, where students learn programming logic like loops, conditionals, and functions by moving a dog through a grid before any JavaScript syntax. The course introduces each concept step by step, so students who have never written code can start here comfortably.
Students build a range of programs in Introduction to Computer Science in JavaScript (Corgi). They start by solving Karel the Dog puzzles, then create graphics and animations on a canvas, program mouse and keyboard interactions, and build a fully working Breakout arcade game from scratch. The course ends with an original final project students design and code themselves.
Introduction to Computer Science in JavaScript (Corgi) uses JavaScript because it runs in any web browser with nothing to install, and it makes visual, interactive results easy to see right away. Students can draw graphics, animate them, and build games in the browser, which keeps a first CS course engaging while teaching the core concepts found in any programming language.
Both are beginner CS courses from CodeHS that need no prior experience; the main difference is language and style. Introduction to Computer Science in JavaScript (Corgi) starts with Karel the Dog and leans into browser graphics, animation, and games, while Introduction to Python Programming teaches the same fundamentals in Python, known for readable, text-based syntax. Choose the one that fits your pathway.
No. Teachers do not need a computer science background to teach Introduction to Computer Science in JavaScript (Corgi). CodeHS provides lesson plans, answer keys, example solutions, and a teacher dashboard, plus optional professional development designed for teachers with limited or no programming experience. Many teachers learn alongside their students using the built-in resources.
Yes. Introduction to Computer Science in JavaScript (Corgi) prepares students for the CodeHS JavaScript Level 1 Certification and includes a built-in practice module with review quizzes so students can build toward the certification as they learn the fundamentals of programming in JavaScript.
After Introduction to Computer Science in JavaScript (Corgi), CodeHS recommends the AP Computer Science pathway: AP Computer Science Principles, then AP Computer Science A. It also feeds a web development pathway into Web Development and Mobile Apps. Students can even take Introduction to Python Programming next; many concepts carry over, but its different approach makes it a great way to learn a second language and see how the same ideas apply.
