CS546-Lab 3 Solved

You will be creating three .js files: people.js , stocks.js and app.js .

Network JSON Data
You will be downloading JSON files from the following GitHub Gists:people.json

(https://gist.githubusercontent.com/graffixnyc/a1196cbf008e85a8e808dc60d4db7261/raw/9fd0d1a4d7846b   stocks.json (Links to an external site.)

(https://gist.githubusercontent.com/graffixnyc/8c363d85e61863ac044097c0d199dbcc/raw/7d79752a9342ac

 For every function you write, you will download the necessary JSONs with axios . DO NOT just save the data into a local file, you MUST use Axios to get the data. Here is an example of how to do so:async function getPeople(){  const { data } = await axios.get('https://.../people.json')   return data // this will be the array of people objects }

Instead of making the request in every single function, remember that code reuse is key, so if you see you are making the same axios request in all of your functions, it's best to put it in a function like noted above and then calling that function in all the functions that need to get the data from whichever json file you're working with.  Always do this when you see you are doing the same thing over and over again in multiple different places.  It's much easier to maintain.  Say if the URL of the file ever changes, then you only need to change it in one place, not 10 different places.people.js

This file will export the following four functions:getPersonById(id)
  This will return the person for the specified id within the people.json array.  Note: The id is case sensitive.

You must check:
That the id  parameter exists and is of proper type (string).  If not, throw an error.
 If the id exists and is in the proper type but  the id is not found in the array of people, throw a 'person not found' error.

 await getPersonById(-1); \\ Throws Error  await getPersonById(1001); \\ Throws Error  await getPersonById();\\ Throws Error await getPersonById('7989fa5e-5617-43f7-a931-46036f9dbcff');\\ Throws person not found ErrorsameStreet(streetName, streetSuffix)

 For this function, you will return an array of people objects who live or work on the same street name with the same suffix from people.json BOTH the street name and the street suffix MUST match! You must return at least two people, so if there are not 2 or more people that live on the same street for the parameters provided you will throw an error.

You must check:

That the streetName and streetSuffix parameters exists and are of proper type (string). If not, throw an error.

 If there are not at least two people that live on the same street and street suffix, you will throw an error.

    id: d78816b3 c06e 436f a9d1 bb60ec60711d ,   first_name: 'Emlynn',   last_name: 'Sawter',   email: 'esawter3w@diigo.com',   ip_address: '47.160.8.36',   ssn: '811-02-3739',   date_of_birth: '01/12/2016',   address: {     home: {       street_number: '889',       street_name: 'Utah',       street_suffix: 'Pass',       city: 'Santa Barbara',       state: 'CA', 

      zip: '93150'     },     work: {       street_number: '518',       street_name: 'Sutherland',       street_suffix: 'Point',       city: 'Saint Louis',       state: 'MO',       zip: '63180' 

  id: '91bef464-b2ee-4c18-8d9d-0781d30a3bcb',   first_name: 'Billie',   last_name: 'Lude',   email: 'bludebs@trellian.com',   ip_address: '157.196.205.99',   ssn: '242-68-1386',   date_of_birth: '09/08/1990',   address: {home: {       street_number: '2',       street_name: 'Sutherland',       street_suffix: 'Point',       city: 'Baton Rouge',       state: 'LA',       zip: '70820'     },     work: {       street_number: '5',       street_name: 'Nobel',       street_suffix: 'Plaza',       city: 'Whittier',       state: 'CA',       zip: '90605' 

}, {   id: '2290f8ad-37b8-4f39-9eb4-a89ed1792887',   first_name: 'Armando',   last_name: 'Pomery',   email: 'apomerydt@msu.edu',   ip_address: '36.101.120.25',   ssn: '381-67-4007',   date_of_birth: '08/28/1975',   address: {     home: {       street_number: '1',       street_name: 'Walton',       street_suffix: 'Parkway',       city: 'Young America',       state: 'MN',       zip: '55573' 

manipulateSsn()
   For this function, you must convert all the SSN's to numbers (removing the dashes) then sort each person's SSN field from lowest to highest digit.  For example, a SSN of: "125-71-1069" would become the number 11125679 .  Note: If the sorted SSN's first number(s) is/are  0, Javascript will drop the leading 0's.  This is expected.  the SSN of: "689-26-5619" would become: 125666899  you will then return an object that contains the person's name (first and last name) with the highest number, the person's name (first and last name) with the lowest number and the Math.floor of the average from all people:

You will return an object in the following format:
sameBirthday(month, day)
 This function will take in the month and day of a birthday: sameBirthday(09, 25) and it will return an array of strings with all the people who were born in that month, on that day. You will show each person's first and last name as one string for each person as shown in the output below.

You must check:
That the month and day parameters exists and are of proper type (numbers). If not, throw an error. (If a string is passed in, you can try to parse that into a valid number first, if it's a valid number, then you can check the following checks, if it cannot be parsed into a number, throw an error.
That the month parameter is 01-12 (or 1-12 without leading zeros), if not, throw an error  That the day parameter is valid for that month. i.e. if month = 9 then day cannot be >= 31 since there are only 30 days in September.  If month = 02 then day cannot be >= 29 since there are only 28 days in February.  (You do not have to take leap year into account).

If there are no people with that birthday, throw an error

await sameBirthday(09, 25); \\ Returns: ['Khalil Ovitts',  'Erny Van Merwe', 'Emanuel Saben', 'Iorgo s Tembridge'] 

await sameBirthday(9, 25); \\ Returns: ['Khalil Ovitts',  'Erny Van Merwe', 'Emanuel Saben', 'Iorgos Tembridge'] 

await sameBirthday("09", "25"); \\ Returns: ['Khalil Ovitts',  'Erny Van Merwe', 'Emanuel Saben', 'I orgos Tembridge'] because the parameters can be parsed into valid numbers. await sameBirthday(09, 31); \\ Throws Error: There are not 31 days in Sept await sameBirthday(13, 25); \\ Throws Error: Month > 12 

 await sameBirthday(02, 29); \\ Throws Error: There are not 29 days in Feb await sameBirthday("09", "31"); \\ Throws Error: There are not 31 days in Sept await sameBirthday("      ", "25"); \\ Throws Error await sameBirthday(); \\ Throws Error: stocks.js

This file will export four functions:listShareholders()
  For this function, you will return an array of objects of all the stocks. You will list all the stocks from  stocks.json , but instead of displaying the userid's of the shareholders, you will look up that userid  in  people.json and return that user's first name and last name in the return object instead:

Note: If a stock has no shareholders, you will return an empty array as shown in the example function call output below.

An example of one of the stocks objects (remember, this function will return an array of ALL the stocks in this format:

Original Stock object:

  "id": "7283e5d6-7481-41cb-83b3-5a4a2da34717", 

  "stock_name": "Aeglea BioTherapeutics, Inc.", 

  "shareholders": [  {"userId": "d8867404-3006-4b09-bb13-1836f88217e2","number_of_shares": 55},  

    {"userId": "2a9896a4-9f83-4478-bdc4-bc528fde97a4","number_of_shares": 449},  

     {"userId": "77f18859-4f6e-451d-ad4d-137e10084bf7","number_of_shares": 120},  

    {"userId": "76ed376e-d673-422d-912d-aefba645bae7","number_of_shares": 14},  

    {"userId": "e9db7f4e-d1e1-4eac-a329-16fc7e9e8b82","number_of_shares": 25} 

Would returntopShareholder(stockName)
  Given the stockName provided, you will find the company from stocks.json  and will return the name of the shareholder from people.json that has the most shares and the number of shares they own.

Make sure to follow the example output string below exactly.

You must check:
  That stockName  parameter exists and is of the proper type (string). If not, throw an error.

 You must check to make sure the stockName parameter is not just empty spaces:  If it is, throw an error.

    If the stock name cannot be found in stocks.json for the supplied stockName parameter, then throw an error.

 NOTE: If the stock name is found in stocks.json but there are no shareholders you will return:

"stockName currently has no shareholders." (replacing stockName with the name of the stock as shown in the example below)

await topShareholder('Aeglea BioTherapeutics, Inc.');  

 \\ Returns: "With 449 shares in Aeglea BioTherapeutics, Inc., Caresse Clissett is the top shareholde r." 

await topShareholder('Nuveen Floating Rate Income Fund');  

\\ Returns: "With 372 shares in Nuveen Floating Rate Income Fund, Thorstein Sarjeant is the top shar eholder." 

await topShareholder('Powell Industries, Inc.');  

\\ Returns: "Powell Industries, Inc. currently has no shareholders."

NOTE: The quotes are just to denote that your function returns a string do not return it with extra  quotes around it.  

However, the exact format of the string needs to be precise including case, spacing and punctuation.  await topShareholder(43); \\ Throws Error await topShareholder('     '); \\ Throws error await topShareholder('Foobar Inc'); \\ Throws error No stock with that name await topShareholder(); \\ Throws Error listStocks(firstName, lastName)
 

Given a firstName and lastName , find the person in the people.json array, then, if they are found, get their ID and find out how many company stocks they own and the number of shares for each from  stocks.json .  You will return an array of objects with the stock name and the number of shares they own in each company.

You must check:

   That firstName and lastName  parameters exists and are of the proper type. (strings). If not, throw an error.

That firstName and lastName  parameters are not just empty strings

 That the person specified exists in the people.json array. If not, throw an error.

That the person specified owns shares in at least one company. If not, throw an errorawait listStocks("Grenville", "Pawelke" );  

// Returns: 
  {stock_name: "PAREXEL International Corporation", number_of_shares: 443}, 

  {stock_name: "Vanguard Russell 2000 ETF", number_of_shares: 59}, 

  {stock_name: "National CineMedia, Inc.", number_of_shares: 320}, 

  {stock_name: "CombiMatrix Corporation", number_of_shares: 434} 

await listStocks('Patrick', "Hill"); // Throws Error because Patrick Hill is not in people.jsonawait listStocks( Patrick , Hill ); // Throws Error because Patrick Hill is not in people.json await listStocks(); // Throws Error await listStocks("foo"); // Throws Error  await listStocks("      ", "        "); // Throws Error await listStocks(1,2); // Throws ErrorgetStockById(id)
 

This will return the Stock for the specified id within the stocks.json array.  Note: The id is case sensitive.

You must check:
  That the id  parameter exists and is of proper type (string).  If not, throw an error.

 If the id exists and is in the proper type but  the id is not found in the array of stocks, throw a 'stock not found' error.
await getStockById(-1); \\ Throws Error  await getStockById(1001); \\ Throws Error  await getStockById();\\ Throws Error  await getStockById('7989fa5e-5617-43f7-a931-46036f9dbcff');\\ Throws stock not found Error app.js

This file is where you will import your functions from the two other files and run test cases on your functions by calling them with various inputs.  We will not use this file for grading and is only for your testing purposes to make sure:
