## What it is
mustache.js is a zero-dependency JavaScript implementation of the Mustache logic-less template system, usable in browsers, Node.js, and CouchDB views, and also as a CLI tool. It expands {{mustache}} tags in templates using values from a view object, with no if/else or loop logic.

## Use cases
- render mustache templates in javascript
- logic-less html templating
- generate html from templates and data
- render templates in node.js
- use mustache templates in the browser
- render templates from the command line
- template config files or source code

## When to choose
- you want simple, logic-less templating with no dependencies
- you need templates that work in browser, Node.js, and other JS environments
- you want to enforce separation of logic and presentation
- you need a spec-compliant mustache implementation in JavaScript

## When to avoid
- you need conditional logic, loops with filters, or complex control flow in templates
- you want a full-featured templating engine like Handlebars, EJS, or Jinja-style features
- you need performance-optimized rendering for very large template volumes
