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

CREATE 3 JS PROMISES USING ASYNC/AWAIT, TRY/CATCH BLOCKS.

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

Create a simple Temperature calculator that will convert the temperature in Fahrenheit to Celcius Kelvin. Your calculator must include:

• A field for the user to enter the temperature;
• A button that when clicked, makes the converted answer appear.
• You must include index.html, style.css, and index.js files.
• Comments throughout every file.
• Buttons should include hover effects, and fields should clearly "focus" when in use.
• Clean and professional creative styling.

JAVASCRIPT Code

let myFormEl = document.getElementById("myForm");

let nameEl = document.getElementById("name");

let nameErrMsgEl = document.getElementById("nameErrMsg");

let passwordEl = document.getElementById("password");

let passwordErrMsgEl = document.getElementById("passwordErrMsg");

let resultErrMsgEl = document.getElementById("resultMsg");

nameEl.addEventListener("blur", function(event) {

  if (event.target.value === "") {

    nameErrMsgEl.textContent = "Required*";

  } else {

    nameErrMsgEl.textContent = "";

  }

});

HTTP Requests & Responses

Background Image:

https://assets.ccbp.in/frontend/dynamic-webapps/book-search-bg.png

Books URL: https://apis.ccbp.in/book-store

Example:

https://apis.ccbp.in/book-store?title=IndiaQuery ParameterValuetitleValue of the searchInput element. Example: India

Method: GET

It should pass test conditions:

When a value is provided in the HTML input element with id searchInput and Enter Key is pressed, an HTTP GET request should be made to the Books URL with the query parameter 'title' as the value of the searchInput element

When the HTTP GET request is successful, then the searchResults element should consist of HTML image elements with src attribute value as the value of key 'imageLink' and HTML paragraph elements with text content as the value of key 'author' from HTTP response

Library Management

In this assignment, let's build a Library Management page by applying the concepts we learned till now.

Product of array Items

given an array integers,write JS program to get the product of the integers in the given array.

input

the input will be containing single line integers.

output

the output should be single line containing the product as shown in sample outputs.

input1

[1,2,3]

output1

[1 * 2 * 3 = 6]

input2

[-1, -2, -3]

output2

[-1*-2*-3 = -6]

Note: The Output should be displayed as [1 * 2 * 3 = 6]

"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() {

 let integers = JSON.parse(readLine());

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

 /* Write your code here and log the output */

}

CCBP Login
