This document provides a quick start guide to JavaScript frameworks for developing SharePoint apps. It introduces several popular JavaScript frameworks and libraries including jQuery, Bootstrap, LESS, and Modernizr. jQuery is described as the most popular JavaScript library for easier DOM element selection and AJAX calls. Bootstrap is explained as an open-source framework for developing responsive, mobile-first projects with pre-built CSS and JavaScript components. LESS and SASS are defined as languages that extend CSS with features like variables and mixins. The document also covers validation plugins, polyfills/shims, and provides demo code examples of Bootstrap and validation in SharePoint apps.

19. Modernizr
Detects HTML5 and CSS3 features that your browser supports on
page load
Result of “feature detection” is “yes” or “no”
Adds classes to HTML
https://github.com/Modernizr/Modernizr/wiki/HTML5-Cross-
browser-Polyfills
Support IE6+, Firefox 3.5+, Opera 9.6+, Safari 2+, Chrome

Yepnopejs is deprecated
Modernizr.load({
test: Modernizr.borderradius,
yep : alert("This browser supports border radius."),
nope: 'PIE_IE678.js'
});

21. Respondjs
It loops through the CSS referenced on the page
IE8: re-requests the CSS files using Ajax
Polyfill for CSS min-width and max-width in browsers that don't
support CSS3 Media Queries

22. Polyfills, shims
Shim: a generic code, a library that brings a new API to an older
environment
Polyfill: downloadable code with fallback for functionality that is
not available in your browser

browser-Polyfills
