## What it is
An interactive blog on computer science and web development topics, built with Next.js and TypeScript. Posts feature hands-on visualizations covering subjects like building a key-value database, SVG path commands, Framer Motion animations, compiler tokenizers, and array internals.

## Use cases
- learn how databases work by building one from scratch
- understand SVG path commands interactively
- study how Framer Motion's magic motion and FLIP technique work
- learn how to build a JavaScript tokenizer
- explore how arrays work under the hood
- learn the sliding window algorithm pattern
- find interactive explanations of computer science concepts

## When to choose
- you want interactive, visual explanations of CS and web dev concepts
- you're looking for deep dives into JavaScript tooling like Babel and Framer Motion
- you prefer learning by exploring animations and hands-on examples

## When to avoid
- you need structured courses with exercises and certification
- you want reference documentation rather than narrative blog posts
- you need content in a language other than English

## Facets
- artifact type: learning-resource
- maturity: active
- function: static-site-generator, data-visualization, animation, documentation
- domain: education, web-development, computer-vision, databases
- platform: -
- tags: interactive-blog, nextjs, react, svg-animations, framer-motion, computer-science, tutorials, algorithms, web-server, nodejs, typescript
