Full Stack Web Development - Lab 1: Testing, FizzBuzz, and Fibonacci

Purpose: To run node and npm on the command line, learn about git and TDD, write JavaScript code, and write tests for that code.

Goal: By the end of the lab, you will have downloaded the initial project from GitHub with the git command, run npm multiple different ways, written JavaScript functions and tests using multiple features of the JavaScript language (var, function, if, else, for, return, arrays, and more), and have at least basic working versions of the FizzBuzz and Fibonacci functions.

Testing, FizzBuzz, and Fibonacci

These are classic programming interview questions!

We will start by cloning the repository to your own machine.

Huh? Cloning? What's that?

Cloning is the process where the git tool makes a copy of the code from GitHub on your laptop, including the code's history of changes.

How do I do that?

To start with, open the Terminal application on your laptop. Once you have the terminal window open, you will need to change directories/folders to where you will create the copy of the code on your machine.

Where?

I like to set up a special directory on my machine to hold all my programming projects (~/Code, and ~ is short for your home directory, which is where the Terminal usually starts). Run mkdir Code at the prompt (mkdir = "Make directory"). After you have done that, run cd Code to change the working directory of your shell (the starting location for any command you run). You can verify that it has been changed by running the pwd (print working directory) command.

Then, in your browser, while looking at the page for the lab repository, click the green "Clone or download" button on the right side, make sure "Clone with HTTPS" is displayed in the title of the popup (or, click "Use HTTPS" in the upper right if it is not), and click the button to copy the repository url to your clipboard. Back in your terminal window where you changed the working directory, type git and then paste that repository url in and hit the return key.

You should see something similar to this:

$ git clone https://github.com/betamore/fswd-lab-1.git
Cloning into 'fswd-lab-1'...
remote: Counting objects: 136, done.
remote: Compressing objects: 100% (12/12), done.
remote: Total 136 (delta 5), reused 15 (delta 5), pack-reused 118
Receiving objects: 100% (136/136), 52.11 KiB | 1.18 MiB/s, done.
Resolving deltas: 100% (53/53), done.

Note that the url for the git repository is simply <url of github page>.git.

Now what?

The git tool created the fswd-lab-1 directory inside the working directory of your terminal. Use the cd command again to change the working directory to fswd-lab-1 (Hint: cd fswd-lab-1). Once inside the directory, if you installed the nvm tool, run nvm use.

Actually working with the code

1. Run npm install to install the node modules for the project, then npm test to run the tests.
2. Everything passes! Grab yourself a cookie; you're all done.
3. Yeah, I was kidding. You're not done at all!
4. Open up Visual Studio Code (or your preferred text editor) and look at the files in the code. Tests are in the test/ directory and the function skeletons are in the lib/ directory.
5. The first cases are implemented and tested (fizzBuzz(0) and fib(0)). Start by writing tests for the next case (1) and expand the function to handle it correctly.
6. Then 2, then 3, …
