在此示例代码中，当它读取数组contactList并j显示两者均未定义时，出了什么问题？

const { join } = require('path');
const puppeteer = require('puppeteer');

(async () => {

    // 1. Launch the browser
    const browser = await puppeteer.launch({   
          "args": [
              '--remote-debugging-port=9222'
          ],
          "defaultViewport": {
            "height": 1080,
            "width": 1920
          },
          "headless": false
        });

    // 2. Open a new page
    const page = await browser.newPage();

    // 3. Navigate to URL
    await page.goto('https://');

    await new Promise(r => setTimeout(r, 10000));
    console.log('Ready');

    var contactList = ['cesar','gab','777','81411579','34353'];
    var fLen = contactList.length;
    var j = 0; …

我必须在 nodejs 中使用 aes-128-ecb 加密数据，我的代码是

我正在使用 Crypto 来加密数据

const crypto = require('crypto');

const secret = '1000060000000000';

const cipher = crypto.createCipher('aes-128-ecb', secret);

const ciphertext = cipher.update('9', 'utf8', 'base64')+cipher.final('base64');

console.log("Cipher text is: " + ciphertext);

输出应该是，EtgITaHs6lEvEHBipj08Kg== 但输出是nNzqejauQBnfiDqznGhZ0Q==
