// Today I learned about some intracicies of Map, Set, WeakMap and WeakSet

/**
  Map
  1. Maps can have non-string keys, even objects! Any value is valid, including NaN.
  2. When iterating over Maps, insertion order is preserved for iteration.
  3. Construct a Map from an object using Object.entries(obj). This converts an object to Map's expected format of nested arrays.
  4. Has .keys(), .values(), and .entries() methods.

This gist contains survey results from a survey I created for my Human Computer Interaction course.

This survey was part of the execution of qualitative evaluation for a textual design alternative for an apple pay integration that would select the best credit card for you at purchase time, based on the amount of cash back you would receive from that purchase.

Here is the textual prototype survey participants evaluated:

“This idea is an apple pay integration. This integration will be smart enough that, when you select apple pay at checkout, it will choose the best credit card to use for the type of purchase you are about to make, based on the active cash back rewards you have available to you. It will update your active cash back rewards automatically as they change from quarter to quarter.”

The population for this survey was limited to students in my HCI class. These students are internationally located, but with a high concentration of US residents.

const data = [{isSpecial: true, specialPoints: 10}, {isSpecial: false, specialPoints: 5}, {isSpecial: true, specialPoints: 15}];

// Using filter, return a new array of objects that are "special".

const specialArray = '***write code here***'

// Using map, return a new array that doubles the points of all items from the filtered 'specialArray'

const doublySpecialArray = '***write code here***'
