## What it is
HTM (Hyperscript Tagged Markup) is a tiny JavaScript library that provides JSX-like syntax using standard tagged template literals, requiring no transpiler. It binds to any hyperscript-style h() function, with off-the-shelf bindings for React and Preact and a Babel plugin that compiles it away for production.

## Use cases
- write JSX-like components without a build step
- use React or Preact directly in the browser
- reduce bundle size by compiling template syntax away
- prototype UI components with no tooling
- use JSX-style syntax in environments without transpilers

## When to choose
- you want JSX ergonomics without a build pipeline
- you use Preact or React and want a tiny syntax layer
- you need to run component code directly in modern browsers
- bundle size is critical

## When to avoid
- you already have a full JSX/Babel toolchain
- you need full JSX ecosystem tooling and type checking
- you use a framework without a hyperscript-style createElement
