JavaScript Basics

Purpose

The purpose of this day project is to familiarize yourself with the basic manipulation methods for both arrays and objects. You will also practice creating variables and functions using logic and the content provided during class.

Directions

Fork and clone this repository. Complete all of the exercises in the different folders (arrays, objects,...) file. When you have finished exercises, push your code to GitHub.

Testing

To run the tests you must install mocha, a testing program, and use npm to install dependencies. In your terminal cd to the project directory. Then do the following.

npm install

and when that is finished you can run

npm test

to run the test for the different exercise topics

All test are set to pending initially. To enable a test for a specific exercise either change

xdescribe()

to

describe()

OR to

describe.only()

in the corresponding .test.js file. The former will still show all test, but enable that one, while the latter will only show that one as enabled.

If you have correctly completed the exercise, it will pop up as green with a checkmark. Otherwise, you will have red x's.
