Flattening & case conversion

the given code to get output using array methods flat(),map() and string methods toLowerCase() and toUpperCase().

input

the first line input is an array nestedArray

the second line input is a number depth

output

the output containing an array with words having even lengths in lowercase and odd length in uppercase

input1

['Inspector', ['ANKLE',['HIKE']],'pawn']

output2

['INSPECTOR','ANKLE', 'hike',' pawn']

function readLine() {

 return inputString[currentLine++];

}

function main() {

 const nestedArray = JSON.parse(readLine().replace(/'/g, '"'));

 const depth = JSON.parse(readLine());

/* Please do not modify anything above this line */

 // Write your code here

}

words with vowels

the goal of the code is to get output using array method filter()

input

the input will be single line containing an array wordsList

output

the output should be single line containing an array with filtered words

input1

['Sword', 'Myth', 'Patient' ,'Rhythm] output2

['Sword', 'Patient']

"use strict";

process.stdin.resume();

process.stdin.setEncoding("utf-8");

let inputString = "";

let currentLine = 0;

process.stdin.on("data", (inputStdin) => {

 inputString += inputStdin;

});

process.stdin.on("end", (_) => {

 inputString = inputString.trim().split("\n").map((str) => str.trim());

 main();

});

function readLine() {

 return inputString[currentLine++];

}

function main() {

 const wordsList = JSON.parse(readLine().replace(/'/g, '"'));

 const vowelsList = ["a", "e", "i", "o", "u"];

// Write your code here

  }

the goal of this code is to quickly get you off the ground with the array method map().

input

the input will be single line containing an array myArray.

output

the output will be single line containing the newArray.

constaints

Strings should be given in quotes

input1

[ 1, 'David' 10, {'points':97}, 25, 'alphabet', true]

output1

[2, 'string' 20, 'object', 50, 'string', 'boolean']

"use strict";

process.stdin.resume();

process.stdin.setEncoding("utf-8");

let inputString = "";

let currentLine = 0;

process.stdin.on("data", (inputStdin) => {

 inputString += inputStdin;

});

process.stdin.on("end", (_) => {

 inputString = inputString.trim().split("\n").map((str) => str.trim());

 main();

});

function readLine() {

 return inputString[currentLine++];

}

function main() {

 const myArray = JSON.parse(readLine().replace(/'/g, '"'));

Bob a builder has come to you to build a program for his business. He needs to determine the square footage of a room in order to buy materials and calculate costs. Bob charges $125 per square metre. The program is going to ask the user to enter the name of a room. It will then ask for the width and length of the room (in meters) to be built. The program will calculate the room area and use this information to generate an approximate cost. Your program will display the room, the total area and the approximate cost to the screen.

Using Pseudocode, develop Javascript for this problem.

Double the numbers

the goal of this code is to get quickly off the ground with array method map().

input

• the input will be single line containing an array myArray

output

• the output will be single line containg the newArray

constraints

• strings should be given in quotes

sample input1

[1, 'David', 10, {'points':97}, 25, 'alphabet', true]

sample output1

[2, 'string' 20, 'object', 50, 'string' 'boolean']

function readLine() {

 return inputString[currentLine++];

}

function main() {

 const myArray = JSON.parse(readLine().replace(/'/g, '"'));

/* Please do not modify anything above this line */

 // Write your code here

}

the goal of this code is to quickly get you off the ground with Creating and Consuming Promises.

input

• the first line of input is containing a boolean isHotWaterReady
• the second line of input is containing a boolean isBreakfastReady

output

• the output could be multiple strings with the appropriate response in seperate lines

based on inputs

sampleinput1

true

true

sampleoutput1

Taken Shower

Had Breakfast

Got to Work

function main() {

 const isHotWaterReady = JSON.parse(readLine());

 const isBreakfastReady = JSON.parse(readLine());

/* Please do not modify anything above this line */

 // Write your code here

 const takingShower = () => {

   return new Promise((resolve,reject) => {

     isHotWaterReady ? resolve("Taken Shower") : reject ("Hot Water Not Ready")

   });

 }

 const breakFast = () => {

   return new Promise((resolve,reject) => {

      isBreakfastReady ? resolve("Had Breakfast") : reject ("Breakfast Not Ready")

   });

 }

the goal of this coding exam is to quickly get off you the ground with the array method every().

input

• the input will be single line containing an array of objects candidatesList

output

• the output should be single line containing an array with names of the selected candidates.

input1

[{'name': 'Blake Hodges', 'points':[76, 98, 88, 84]}

output1

['Blake Hodges]

WEB230 JavaScript 1 Assignment 3 - Quiz Average In this assignment we will write a JavaScript program to calculate the average of a set of quiz marks. Instructions 1. Create variable containing an array that will contain five or more numbers that represent the marks on quizzes. It is assumed that all quizzes will be out of 10 so the numbers must be values between 0-10. 2. Create a function that will take the array as an argument and return the average of the quizzes. 3. Output a text message with the values of the quizzes, space seperated without brackets. Use a template literal when constructing the output strings (AKA back-ticks, template literals are explained in the section on Strings in Chapter 1). 4. Output a text message with the final average rounded to one decimal place. Again use a teplate literal. 

the goal of this code is quickly to get off the ground with classes.
