## What it is
Civet is a programming language that is a superset of TypeScript, compiling to TypeScript or JavaScript with concise syntax like indentation-based blocks, pattern matching, and pipelines. It ships as an npm package with a CLI compiler/REPL, Node ESM/CJS loaders, build-tool plugins (Vite, esbuild, Rollup, etc.), and editor integrations.

## Use cases
- write TypeScript with less typing
- transpile concise syntax to TypeScript
- run .civet scripts directly in Node
- add pattern matching and pipe operators to JavaScript
- gradually modernize a CoffeeScript codebase
- use indentation-based syntax with full TS type checking

## When to choose
- you want TypeScript's type system but prefer concise, indentation-based syntax
- you want TC39-proposal features like pattern matching and pipes today
- you want 99% JS/TS compatibility so existing tooling and code keep working

## When to avoid
- your team must write plain TypeScript/JavaScript with no build step
- you need a mature ecosystem with guaranteed long-term support
- you dislike nonstandard syntax or extra transpilation in your toolchain
