About
JavaScript is a scripting language and programming language for the web that enables developers to build dynamic elements on the web. Over 97% of the websites in the world use client-side JavaScript. JavaScript is one of the most important scripting languages on the web. Strings in JavaScript are contained within a pair of either single quotation marks '' or double quotation marks "". Both quotes represent Strings but be sure to choose one and STICK WITH IT. If you start with a single quote, you need to end with a single quote. There are pros and cons to using both IE single quotes tend to make it easier to write HTML within Javascript as you don’t have to escape the line with a double quote. Let’s say you’re trying to use quotation marks inside a string. You’ll need to use opposite quotation marks inside and outside of JavaScript single or double quotes.

About
Underscore is a JavaScript library that provides a whole mess of useful functional programming helpers without extending any built-in objects. Underscore provides over 100 functions that support both your favorite workaday functional helpers like map, filter, and invoke, as well as more specialized goodies like function binding, javascript templating, creating quick indexes, deep equality testing, and so on. You may choose between monolithic and modular imports. The project is hosted on GitHub. You can report bugs and discuss features on the issues page or chat in the Gitter channel. Underscore 1.x is backward compatible with any engine that fully supports ES3, while also utilizing newer features when available. Collection functions work on arrays, objects, and array-like objects. We have recent confirmation that the library is compatible with Adobe ExtendScript. There is support code present for IE 8, which we will retain in future Underscore updates.
