About StudyGrid
StudyGrid is a free site for learning to code. Python, HTML, CSS, JavaScript, C, C++, Java, and TypeScript, each with lessons and an editor in the browser.
What this site is
StudyGrid is a set of tutorials you can read without signing up. Most chapters are one idea, a short explanation, and some code you can run. If the example can run in the browser, a button under it opens the matching editor.
Python prints (and can plot). HTML shows a live page. CSS styles that page. JavaScript can change the page and log to a console. C uses gcc. C++ uses g++. Java uses javac. TypeScript uses tsc, then runs. Those editors are separate pages. The site lives at studygrid.in.
What you can learn here
- Python — from syntax through data science, Django, and ten projects.
- HTML — tags, layout, forms, a live preview, and ten pages to finish.
- CSS — selectors, the box model, flex, grid, and ten pages to style.
- JavaScript — variables, functions, the DOM, events, and ten small apps.
- C — C17 with gcc in the browser, including pointers, structs, and ten programs.
- C++ — C++17 with g++, classes, the STL, and ten programs.
- Java — Java 21 with javac, classes, collections, and ten programs.
- TypeScript — types, classes, generics, and ten programs, with tsc in the browser.
- Kids — Basic, Intermediate, and Advanced Python for children.
- Vibe Coding — pick an AI coding tool, then build without skipping the review.
- General Blog — learning to code: practice, debugging, and first projects.
- AI at Work — essays on using AI at work.
How a lesson is built
Previous and Next keep you on a path. The sidebar lists the rest of the track. On a phone you can hide it if you want more room. If an example needs a local install (a Django server, a real database, files on disk), the lesson says so.
Who it is for
People starting a first language, and people who already code in one language and want another without setting up a toolchain first. The in-browser editors have limits. They are for learning, not for shipping a production app.
