The Root of All Code vs AlgoLens

Ever wonder what programming looks like outside the mainstream? The Root of All Code introduces you to languages like APL, Forth, Prolog, and others that approach problem-solving in radically different ways. They're the sorts of languages that go ignored in industry but can dramatically improve your thought process and solutions even if you never deploy a line of them in production. You don't need to master these languages (though you might want to). The goal is to understand the ideas behind them that will sharpen your thinking and improve the code you write every day, in any language. Features: - Explore non-mainstream programming languages and the paradigms they embody - Thoughtful code snippets showing how different languages solve problems - Currently supports nine programming languages - Currently available in English and Spanish Built by a developer, for developers, because the best way to grow is to see how the other half codes.

AlgoLens teaches coding patterns the way they actually click — through real-world stories, interactive visualizers, and guided practice. Instead of memorizing abstract algorithms, see why and where each pattern is used in real software systems: • Fraud detection → Sliding Window • Duplicate payments → HashMap • Undo / Redo → Stack • Recently Played → Arrays • Friends of friends → Graph BFS • Calendar conflicts → Merge Intervals Eight pattern paths so far: • Arrays • HashMaps • Two Pointers • Sliding Window • Stack & Queue • Trees • Graph Basics • Merge Intervals Each lesson includes: • A real-world story that anchors the pattern in memory • An interactive visualizer — step through, play, watch the work happen • Guided practice problems with explanations • An interview-ready breakdown with time/space complexity, vs. brute force, and a Swift code sample in a syntax-highlighted editor Practice mode adds three coding game types: • Fill in the blanks — tap a token, drop it into the right slot • Sort the code — shuffled lines, tap two to swap them into order • Find the bug — read the function, tap the line that doesn't match the title Stack streaks, earn XP, and filter puzzles by the companies that ask similar questions in interviews — Google, Meta, Apple, Amazon, Microsoft. Built for mobile-first learning. iPhone-sized, dark code editor styling, short focused lessons designed for the in-between moments. Understand patterns visually. Remember them through stories. Apply them like real engineers.
