Follow a story
Join Detective Maya on a case. Each small task gives you a reason to use the code, so you understand what it does.
SPOTHUB CODECOMPANION BETA
Coding gets easier.
One small step at a time.
Follow a story. Understand one idea. Try the code yourself. Build confidence with small, guided steps.
Free beta · No installation · Start without an account
AVAILABLE NOW · BETA
Your JavaScript journey starts here.
Begin with messages, values and variables. Build towards functions, objects and asynchronous code, with extra preparation when a new idea needs explaining.
- English, Tanglish or Tamil explanations
- Code editor and output in the same workspace
- Combined coding milestones to practise earlier lessons
- Examples to help you explain your thinking
Understand it. Practise it. Explain it.
Try the code
Read a small example, then write your own program. Run it, inspect the result and use feedback to improve.
Put ideas together
Use earlier ideas in coding milestones. Remember the story, connect it to a project, and practise explaining it in an interview.
You do not need to know coding to begin.
Start at Lesson 1 if you are new. Choose the explanation language that helps you understand; JavaScript code and technical definitions stay in English. A laptop or desktop is recommended for writing code comfortably.
What beta means for you
This is an early release, and we are improving the lessons. Your work saves in this browser, not an online account. Clearing browser data removes it; switching devices does not transfer it. You can download a review file from the workspace, but it cannot restore your progress.
Practice checks help you learn; they are not certification or a guarantee of job readiness. Found something confusing? Tell the SPOTHUB team →
