Day 4: Create a Rectangle Object:-10 Days of Javascript HackerRank Solution

Problem:-

Objective

In this challenge, we practice creating objects. Check out the attached tutorial for more details.

Task

Complete the function in the editor. It has two parameters:  and . It must return an object modeling a rectangle that has the following properties:

• : This value is equal to .
• : This value is equal to .
• : This value is equal to 
• : This value is equal to 

Note: The names of the object's properties must be spelled correctly to pass this challenge.

Input Format

The first line contains an integer denoting . 
The second line contains an integer denoting .

Constraints

Output Format

Return a object that has the properties specified above. Locked code in the editor prints the returned object's , , , and  to STDOUT.

Given a  of  and a  of , the Rectangle object's  is  and its  is .

Solution:-

'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(string => {

return string.trim();

});

main();

});

function readLine() {

return inputString[currentLine++];

}

/*

* Complete the Rectangle function

*/

function Rectangle(a, b) {

this.length = a;

this.width = b;

this.perimeter = 2 * (a + b);

this.area = a * b;

}

function main() {

const a = +(readLine());

const b = +(readLine());

const rec = new Rectangle(a, b);

console.log(rec.length);

console.log(rec.width);

console.log(rec.perimeter);

console.log(rec.area);

}
