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.
• Push your first commit: git commit --allow-empty -m "first commit" && git push.
• Check to see that Codegrade has accepted your git submission.

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 http://localhost:3000
• In a separate terminal, run npm test to run tests.

Steps Required for MVP:

• 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.
• 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.

Submission format

• Submit via Codegrade by committing and pushing any new changes to the main branch.
• 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

Demonstrate your understanding of this week's concepts by answering the following questions:

1. What is the DOM? DOM is an acronym for the Document Object Model. The browser builds this model of a website’s look and behavior when it reads the HTML and Javascript.

2. What is an event? Being literal, an event is a piece of data-– it’s an object that’s created when a user interacts with the DOM, by taking an action such as clicking, scrolling, or moving their mouse.

3. What is an event listener? An event listener is a method that attaches to an element and waits for a user to interact with the element. The method is invoked when the user generates an event.

4. Why would we convert a NodeList into an Array? A NodeList is an “array-like object” and not language-specific. So, Javascript methods that we would often like to use on it are not always available until the NodeList is converted into an array.

5. What is a component? A component is a function that can be used to create a piece of a website– or multiple websites. When you intend to create many similar pieces, you can save time and keep code “DRY” by using a component to create the pieces.
