To properly install a read-only copy of JsObjects first create a directory called ~/Git if it does not already exist:
Note that this directory should be a subdirectory of your home directory.
Now navigate to that directory and clone JsObjects from GitHub:
cd ~/Git git clone https://github.com/charliecalvert/JsObjects.git
All the code in JsObjects is released under the MIT license.
Students in my classes, and readers of my text, should have JsObjects setup correctly on their systems. In particular, I suggest creating a virtual machine that runs the Ubuntu Linux OS. You can then install JsObjects on it and perform the necessary setup without causing any conflicts with code on your primary machine. You don't have to do things this way, but it is perhaps the simplest course of action for many readers.
On modern Ubuntu based Linux systems, you can quickly and easily perform the setup by running the UbuntuSetup script. I have tested this script extensively, however, I think it is best to run it on a freshly minted VM running in a tool such as VirtualBox or VMware. When I install a fresh copy of Ubuntu, Lubuntu or Mint either in a VM or directly to metal, this is usually the first thing I do. I hesitate recommending that you do this on other systems simple because it adds the commands specified here to your .bashrc file. The script also installs a fresh copy of NodeJs. There are various ways to install node, and it is probably not best to mix one with another. Hence I recommend a fresh install of an Ubuntu based distro before proceeding, unless you are sure you do not have Node installed already.
If you are using Pristine Lubuntu then this script has already been run, and running it a second time will rarely cause damage unless you have done something odd your instance of Pristine Lubuntu. If all all else fails, I strongly recommend just downloading a fresh copy of Pristine Lubuntu.
NOTE: This script will save your current .bash_aliases file as .bash_aliases.old and will install a new .bash_aliases file. It will also append text to the end of your .bashrc file.
Choose either the first or second option from the script's menu:
Ubuntu a) Run All (Basic and Node Related) b) Run Basic Setup (All but Node Related)
The first will install node and set up your system for work in my classes. The second will set up your system, but will not install node.
When you are done, type the following:

NOTE: It is best not to edit the files in a repository that you do not own, such as JsObjects. If you want to edit a file or other entity such as a project, I suggest coping it to another location on your hard drive. If you have a bit of experience with Git, then an alternative is to create a fork of the repository.
JsObjects is big and hard to navigate. I have, however, created a series of Bash aliases that can help you quickly find what you are looking for by only entering a few keystrokes.
These aliases are stored near the bottom of my .bash_aliases file, which is found here. The .bash_aliases file is referenced in your .bashrc file and should be run automatically whenever you open a Bash shell. As implied above, your .bashrc file can also be processed by typing:
On Windows, run the install found at the nodejs site.
On Linux, you can run the UbuntuAndCloudNineSetup described above.

There are a few grunt tasks defined. One would be:
npm run lint
This will use Grunt to lint the files in the root JsObjects directory.
