[프로그래머스/js] 직각삼각형 출력하기

내 풀이

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

let input = [];

rl.on('line', function (line) {
    input = line.split(' ');
}).on('close', function () {
    const InputNumber = Number(input[0]);
    
    for(var i=1; i<=InputNumber; i++){
        console.log('*'.repeat(i));
    }
});
