## What it is
Handlebars.js is a JavaScript templating library, largely compatible with Mustache, that compiles templates into fast-executing JavaScript functions. It adds features like nested paths, helpers, and block expressions for building semantic templates.

## Use cases
- render html templates from json data
- mustache-compatible templating in javascript
- precompile templates for faster page load
- server-side html generation in node
- build semantic templates with helpers and partials

## When to choose
- you need logic-light, Mustache-compatible templates
- you want fast compiled template rendering in Node or the browser
- you need helpers, partials, and block expressions

## When to avoid
- you need a full frontend framework with reactive state
- you prefer logic-heavy templating with embedded code
- you need streaming or async template rendering out of the box

## Facets
- artifact type: library
- maturity: stable
- function: templating, parser
- domain: web-development, frontend, developer-tools
- platform: browser, cross-platform
- tags: handlebars, mustache, template-engine, html-templating, precompilation, nodejs, javascript
