 ## Protecting the $ Alias and Adding Scope
 
-The `$` variable is very popular among JavaScript libraries, and if you're using another library with jQuery, you will have to make jQuery not use the `$` with `jQuery.noConflict()`. However, this will break our plugin since it is written with the assumption that `$` is an alias to the `jQuery` function. To work well with other plugins, _and_ still use the jQuery `$` alias, we need to put all of our code inside of an [Immediately Invoked Function Expression](http://stage.learn.jquery.com/javascript-101/functions/#immediately-invoked-function-expression-iife), and then pass the function `jQuery`, and name the parameter `$`:

 ## Testing Type
 
-As seen in [the JavaScript 101 section](http://learn.jquery.com/javascript-101/testing-type/) the `typeof` operator can be inconsistent or confusing. So instead of using `typeof`, jQuery offers utility methods to help determine the type of a value.
