JavaScriptmas: Context & History

In early 2024 the MDN Curriculum was released to teach web development fundamentals. To complement the curriculum, a partnership with Scrimba produced a festive series of coding challenges called JavaScriptmas. Running from December 1st to December 24th, each day a new problem appears at midnight UTC, offering a short video introduction, starter code, and a chance to practice JavaScript, DOM work, CSS, and basic security concepts.

Implementation & Best Practices

Before diving into any specific technique, follow this three‑step roadmap: first, prepare a consistent development environment second, adopt a systematic problem‑solving approach third, verify and share your solution according to the platforms guidelines.

Preparing the Development Environment

Use the built‑in Scrimba editor for immediate feedback. Ensure your browser supports the latest JavaScript features and that you have a reliable internet connection for the screencast videos. Optional: clone the starter repository to a local IDE for advanced debugging.

Systematic Problem‑Solving Approach

Read the challenge description carefully, then outline the required inputs and expected outputs. Write pseudocode to map the algorithmic steps before filling in the starter code. Test edge cases manually and with the provided test suite.

Verification and Submission

Run the built‑in tests all must pass before submission. Submit directly on Scrimba or share on social platforms using javascriptmas. Each correct entry counts toward the prize draw.

Key Takeaways

• Consistent environment reduces friction when switching between daily tasks.
• Structured thinking improves accuracy and speed.
• Timely submission secures eligibility for the prize selection.
