Code Forge vs queri

Code Forge teaches you programming the way you'd actually want to learn it: short lessons, real code you can run, and small challenges that keep your brain awake. The app is built around three paths. 1. Programming basics Start from zero with TypeScript. Variables, functions, classes, conditionals, loops, lists, dictionaries, randomness, and the rest of the foundations. Every concept comes with a runnable example. Change the code, hit run, and see what happens. The built-in compiler turns each lesson into a tiny playground instead of a wall of text. 2. Game development Once the basics click, you move into how games actually work. What a game engine is. The game loop. Update vs fixed update. Delta time. Input, state, simple physics. You'll read and tweak real examples, and by the final chapters you're putting small games together yourself. 3. Shaders The last path goes into the part most tutorials skip. What a shader is, how vertex and fragment stages fit together, the math behind them, and the small algorithms that make things glow, ripple, or distort. Examples are interactive so you can poke at the numbers and watch the picture change. Mini challenges at the end of each chapter Every lesson ends with optional mini games and short puzzles. Pattern matching, quick logic rounds, small coding tasks. Quizzes A separate quiz mode lets you test what stuck. Questions cover programming, game dev, and shaders, sorted by topic, so you can drill the area you're less sure about instead of guessing through everything. Who it's for - Beginners who want a calm, structured way into programming without buying a textbook - Self-taught developers who want to finally understand game loops and shaders - Students who want extra practice alongside their college courses - Anyone who learned to code years ago and wants a refresher with real examples What makes it different - Runnable code inside every lesson - Three full paths that actually connect: code, then games, then shaders - Short chapters you can finish on a coffee break - Optional mini games for the days you want something lighter - Quizzes for when you want to prove to yourself you got it You don't need any prior experience. If you've never written a line of code, the first chapter assumes that. If you already know the basics, you can jump ahead to game dev or shaders and use the early lessons as a refresher.

Type SQL. Run it. See real rows. queri is a SQL course where every single lesson ends with a query you write yourself and run against a real database sitting on your phone. No signup. No internet needed. No copying answers off a video. WHY THIS IS DIFFERENT Most SQL apps ask you to pick A, B, C or D. You can pass a multiple-choice test on JOINs and still freeze the first time you face a real table. queri never asks you to recognise SQL — it asks you to write it, then runs what you wrote and checks the rows that came back. HOW A LESSON WORKS 1. A short, plain-English explanation of one idea. No walls of theory. 2. A real task on a real dataset: "list every customer in New York". 3. You type the query. You run it. You see the actual rows. 4. queri compares your result to the correct one and tells you what is off. 5. Stuck? A hint that points at your specific mistake, not a generic nudge. WHAT YOU WILL LEARN - SELECT: pull columns out of a table - WHERE: filter with AND, OR, BETWEEN, IN, LIKE and NULL - ORDER BY and LIMIT: sort and slice - COUNT, SUM, AVG, MIN, MAX: aggregate a column - GROUP BY: aggregate per group - JOIN: combine tables, including three-table joins - A capstone: revenue per customer, written from scratch THE DATASET IS REAL You work against a small online-shop database: customers, products, orders and order items, with real rows, real nulls and real messiness. Not three toy rows. The schema is one tap away while you write. WORKS ANYWHERE Everything runs on your device with SQLite. On the metro, on a plane, on a dead connection. Nothing is uploaded. There is no account to create. BUILT FOR A PHONE A SQL key row with the characters you actually need. Results in a table you can scroll sideways. Progress and streak saved locally. FOUR LANGUAGES English, French, Arabic with full right-to-left support, and Spanish. FREE AND PRO The first module and the first eight lessons are free. That is enough to know whether this works for you. queri Pro unlocks the full curriculum. SQL is the one technical skill that outlasts every framework. Learn it by writing it.
