JavaScript Code Daily Challenge #3

About

This is a series of JavaScript Code Daily Challenge. Each day I show a few solutions written in JavaScript. The questions are from coding practice/contest sites such as HackerRank, LeetCode, Codeforces, Atcoder and etc.

'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 both the functions in comment

/**

function getArea(length, width) {
    let area;
    // Write your code here
    area = length*width;
    return area;
}

function getPerimeter(length, width) {
    let perimeter;
    // Write your code here
    perimeter = 2*(length+width)
    return perimeter;
}
