Solution in JavaScript (node.js v5.12) (judge verdict: Runtime Error)

const lines = [];
const readline = require((readline));

const rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout
});

rl.on('line', (input) => {
    lines.push(input);
});

rl.on('close', () => {
    const inputsAsArr = lines.split(' ');
    const sideA = inputsAsArr[0];
    const sideB = inputsAsArr[1];
    const sideC = inputsAsArr[2];

    const outputStr = sideA === sideB === sideC ? 'Yes' : 'No';
    console.log(outputStr);
});
