.filter is a method that takes in a function and filters data based on what we find useful
reminder that .forEach expects a function as its callback
if you want to check if a number is an integer you use the Number.isInteger functionality
using "&&" you can link the requirement functions together in a much more reliable way
Callback arguments can be either defined in-line or declared as a variable before usage
2. About charts in Javascript.
we will be using Charts.JS (similar to papa.parse) by adding a script tag into our html
when working with charts the objects on the left are called the "key" and the objects on the right are called "values; if you want to separate these you must use the object.key or object.value methods
it's important to remember that data wants an array of numbers and labels want an array of strings when you are working with them
