## What it is
yepnope.js is a JavaScript script loader for conditionally loading scripts and CSS based on feature tests, historically bundled with Modernizr as Modernizr.load. The project is officially deprecated; the repo now hosts a minimal replacement script that helps load pre-built conditional bundles rather than loading many resources at runtime.

## Use cases
- conditionally load polyfills based on browser feature support
- load a single optimized build tuned to a user's browser capabilities
- asynchronously inject scripts and stylesheets in the browser
- integrate feature detection with Modernizr to pick the right bundle
- serve per-feature-combination builds from a cached endpoint

## When to choose
- you are maintaining a legacy codebase that already depends on yepnope or Modernizr.load
- you need a tiny script to pick one of several pre-built bundles based on feature tests

## When to avoid
- starting any new project - the authors recommend module bundlers like webpack, browserify, or require.js instead
- you need ordered script execution - the replacement no longer guarantees execution order
- you want actively maintained software with support and security fixes
