A place to practice, deliberately

A code editor, mock interviews, doubt threads, algorithm visualizers, and a cohort leaderboard — everything you need to apply what you have learned.

Code Editor

A full in-browser editor with a real JavaScript runtime. Write, run, and submit solutions without leaving the page.

Schedule a live practice round with a mentor or peer and get specific, actionable feedback.

Post a question while you practice and get help from the community.

Watch sorting, graph, and tree algorithms run. Step forward, pause, and rewind to follow each operation.

Short terminal challenges for grep, awk, find, and jq to build real command-line fluency.

Weekly XP standings within your cohort, so you can measure progress against people on the same path.
