JavaScript Functions

Using the google shoping data used before (also included in this repository) create some useful functions to answer the following questions.

REMEMBER: All functions should take input (data passed into the function as arguments) and give output (using the return keyword).

Functions SHOULD NOT access/modify variables defined outside of the function.

Getting Started

  • Fork and clone this repository
  • Start creating functions in js/google_shopping_functions.js
  • Run node js/google_shopping_functions.js to run your code

Deliverables

Create the following functions.

1.) getItems(objectData)

  • input: json object
  • returns: an array of items

Create a function called getItems that simply returns the items array from the google product object.

Note all other functions (below) use the return of this function as their input.

2.) getItemsByBrand(items, brand)

  • input: an array of items, a string of a brand to filter with
  • returns: an array of items (of a specific brand)

Create a function called getItemsByBrand that takes an item array returns a new array of all items of a specified brand.

Test this function by searching for Sony, Canon, Nikon and Panasonic.

3.) getItemsByAuthor(items, author)

  • input: an array of items, a string of an author to filter with
  • returns: an array of items (of a specific author)

Create a function called getItemsByAuthor that takes an item array and returns a new array of all items by a specified author.

Test this function by searching for Target, CDW, eBay

4.) getAvailableProducts(items)

  • input: an array of items
  • returns: an array of items (that are available)

Create function called getAvailableProducts that takes an item array and returns an array containing all of the available products (an available product is one with at least one availability of "inStock" in the inventories array)

5.) Use your functions

Use the functions you created in 1 - 5 to ouput (console.log) the following lists of items.

  • All items made by Sony.
  • All items made by Sony that are available.
  • All available items by the author "Adorama Camera"
  • All items made by Nikon with the author eBay.

** Example Function Usage**

//verbose -- outputs all cannon products
var items = getItems(data);
var cannonItems = getItemsByBrand(items, 'Cannon');
console.log(cannonItems);

//single line version -- does the same as above
console.log(getItemsByBrand(getItems(data), 'Cannon'));

Further

Give the ability for the user to give the search term in the terminal:

node js/google_shopping_functions.js Nikon

Get the process.argv[2] user input and use it as the search term input to your getItemsByBrand function.

Further

If no results were found, let the user know.

Further

Ask the user if they want to do or see the following things, then do that thing based on what the user entered:

  1. The number of product items

  2. The country of each item

  3. Total price of all inventory

  4. Search for one of the things above

An example command could be:

node js/google_shopping_functions.js searchByBrand Nikon

Further

Let the user enter in a maximum or minimum price. Only show them items that correspond.
