Applied JavaScript Sprint Challenge

Read these instructions carefully. Understand exactly what is expected before starting this Sprint Challenge.

This challenge allows you to practice the concepts and techniques learned over the past sprint and apply them in a concrete project. This sprint explored Applied JavaScript. During this sprint, you studied DOM and components. In your challenge this week, you will demonstrate your mastery of these skills by creating an online Lambda newspaper.

This is an individual assessment. All work must be your own. Your challenge score is a measure of your ability to work independently using the material covered through this sprint. You need to demonstrate proficiency in the concepts and objectives introduced and practiced in preceding days.

You are not allowed to collaborate during the sprint challenge.

Project Set Up

Fork and clone the repo. Delete your old fork from Github first if you are repeating this Unit.
Open the assignment in Canvas and click on the "Set up git" option.
Follow instructions to set up Codegrade's Webhook and Deploy Key.
Push your first commit: git commit --allow-empty -m "first commit" && git push.
Check to see that Codegrade has accepted your git submission.

For a step-by-step on setting up Codegrade see this guide.

Project Instructions

Introduction

You are going to create a Lambda Newspaper. Your job is going to be to create the components that make up the newspaper's home page.

In meeting the minimum viable product (MVP) specifications listed below, your project should look similar to the image linked below:

Lambda Times

Instructions

Navigate to the root of the project with your command line.
Run npm install to download the dependencies listed in the package.json file.
Run npm start to compile the project and serve it.
Navigate Chrome to the URL indicated in the output of the npm start command.
In a separate terminal, run npm test to run tests.

Steps Required for MVP:

Step 0 is to link src/index.js to the src/index.html file using a script tag.
Steps 1 and 2 are explained inside the src/components/header.js file.
Steps 3 and 4 are explained inside the src/components/tabs.js file.
Steps 5 and 6 are explained inside the src/components/card.js file.

Important Notes:

Please do not move or rename existing files or folders.
Careful adding your script tag in Step 0: the code inside index.js needs the DOM to be fully built before executing.
Careful if you choose to install Axios using another script tag: the order in which script tags execute is important.
If your development server stops "auto reloading", manually kill it with CTRL+C and restart it.
Do not change the package.json file except to install libraries with NPM (Axios is already in the package.json).
In your solution, it is essential that you follow best practices and produce clean and professional results.
Schedule time to review, refine, and polish your work, including spell-checking and grammar-checking.
It is better to submit a challenge that meets MVP than one that attempts too much and does not.

Stretch Goals:

IMPORTANT: Work on stretch goals in a new branch. You can branch off of <firstName-lastName> by executing git checkout -b stretch.

After finishing your required elements, you can push your work further. These goals may or may not be things you have learned in this module but they build on the material you just studied. Time allowing, stretch your limits and see if you can deliver on the following optional goals:

Submission format

Submit via Codegrade by committing and pushing any new changes.
Create a pull request to merge <firstName-lastName> branch into main.
Please don't merge your own pull request and make sure you are on your own repo.
Check Codegrade for automated feedback.
Check Codegrade in the days following the Sprint Challenge for reviewer feedback.
Any changes pushed after the deadline will not receive any feedback.

Interview Questions

Be prepared to demonstrate your understanding of this week's concepts by answering questions on the following topics. You might prepare by writing down your own answers before hand.

What is the DOM?
What is an event?
What is an event listener?
Why would we convert a NodeList into an Array?
What is a component?
