 ### Objects
 
 To better understand objects, you really just need to write more of them. The [objects.js](assignments/objects.js) file contains several challenges centered around a theme of interns starting at a new job. The Human Resources team needs information about the new hires. Use your new found object skills answer vital questions for HR.

 ### Arrays
 
 The [arrays.js](assignments/arrays.js) assignment takes us through a large data set of used cars.  You have been asked to help a used car business with some customer requests based on their inventory.  Use for loops and arrays to solve their problems.

 ### Arrow Function Syntax
 
 * [ ] Arrow Function Syntax - [Check out this awesome guide for ES6 arrow syntax](https://medium.freecodecamp.org/when-and-why-you-should-use-es6-arrow-functions-and-when-you-shouldnt-3d851d7f0b26). You will see more and more arrow functions as you progress deeper into JavaScript. Use the [function-conversion.js](assignments/function-conversion.js) file as a helper challenge to showcase some of the differences between ES5 and ES6 syntax.
