An opinionated online glossary of computer science terms written for front-end developers by Dan Abramov. It is a static website (built with CSS) that publishes plain-language explanations of concepts like closures, composition, dynamic dispatch, and memoization.
Use cases
- understand what a JavaScript closure actually is
- look up a plain-English definition of memoization
- learn computer science terminology as a front-end developer
- find an opinionated explanation of composition
- request or vote on definitions for confusing CS terms
- share a clear reference link when explaining a concept to a colleague
When to choose
- you are a front-end or JavaScript developer wanting concise, opinionated explanations of CS concepts
- you prefer short, human-written definitions over long textbook chapters
- you want a shareable link that explains a single term clearly
When to avoid
- you need an exhaustive or neutral reference like MDN or Wikipedia
- you want a structured course with exercises rather than a glossary
- you need definitions for backend, systems, or non-JavaScript-specific topics
