Waiting Games

⏳ 🐰 now, 🐢 in 1 second — set timers like this, and things won't happen in the exact order you wrote them! Watch your scheduled events pop up along the timeline. 🔮 In Predict the Order, read the code and guess what shows up first. Setting a 0-second delay while the line below runs first is the coolest surprise here! A 1-second delay beats a 2-second delay, and if both are set to 1 second, the first one scheduled wins. 🔁 In Repeat, choose how often and how many times to loop. In the final mission, try forgetting to stop on purpose — watching it go forever shows why stop conditions matter. Made with code · Remix this to build your own schedule!
About this app
Do It Later is an interactive coding playground designed to help beginners understand asynchronous execution and timing in programming. Users explore how code execution order changes when scheduling tasks immediately, after a delay, or on a repeating loop. Through hands-on puzzles and sequence prediction challenges, learners discover core concepts like event loops and zero-delay timeouts.
Use cases
- Beginners learning fundamental JavaScript and asynchronous programming concepts
- Coding educators demonstrating event loop mechanics and execution order to students
- Self-taught developers wanting a visual intuition for timeouts and intervals
Features
- Schedule tasks with custom delay intervals on a visual timeline
- Predict code output sequences in interactive execution order quizzes
- Configure repeating interval timers and test stopping conditions
- Inspect live JavaScript code previews matching interactive puzzle setups
