What is node_modules directory in ember.js?

@elisha_langworth 

The node_modules directory in Ember.js is created when you use npm to install packages and dependencies for your Ember.js project. It is where all the modules required by your project are stored, including Ember.js itself, as well as any additional libraries or packages that your project depends on. These modules are typically installed using the npm package manager and are stored in the node_modules directory in your project's root folder. This directory should not be manually modified or deleted, as it contains important dependencies that your project relies on.
