underscore-style prototype cloning

Underscore-style prototype chaining

Cloning the prototype allows the user to conform to the convention of not mutating an object's prototype while extending the flexibility of the prototypal chain.

Lexical scope

Javascript does not have a mechanism to preserve the global namespace, which can lead to namespace collisions and other errors. Foundation uses a one-line initialization script, var foundation = {}, to create an object that can function as a namespace. In Javascript, when an object is declared, an environment record or scope is also created - functions and variables located within the same environment record have access to each other. Objects and functions contain their own environment record. try catch blocks and conditionals do not.

The IIFE was a popular construct used in the development of jQuery and documented in Addy Osmani's JS Design Patterns as the revealing module pattern to help avoid namespace and scope collisions by wrapping a function with an immediately-invoked function - the wrapper is invoked on runtime and functions and variables are declared within the IIFE's scope rather than what is referred to as the global scope.

* This method is several years old and is being produced here to continue the discussion
* about what is considered production-level element attribute toggling.
* Both jQuery and twbs are widely used in production sites and can be used
* as standards for production-level acceptance criteria.
* jQuery is similar to this method - it looks for
* classList first and then falls back to className.
