## What it is
BhaiLang is a dynamically typed toy programming language written in TypeScript, built as an inside joke with Hindi slang keywords like 'hi bhai', 'bol bhai', and 'sahi'. It is distributed as an npm CLI that parses and interprets .bhai files, with an online playground.

## Use cases
- write hello world in a joke programming language
- learn how interpreters and parsers work
- try a toy language in the browser playground
- install a fun CLI language via npm
- teach compiler basics with a simple language

## When to choose
- you want a fun novelty language for demos or learning
- you are studying how a TypeScript parser and tree-walking interpreter are built

## When to avoid
- you need a production-ready language for real software
- you need performance, a rich ecosystem, or long-term support
