How to wait until an element is visible with JavaScript Puppeteer?

To wait until an element is visible with JavaScript Puppeteer, we call waitForSelector.

For instance, we write

const puppeteer = require("puppeteer");

const broswer = await puppeteer.launch();
const page = await browser.newPage();
await page.waitForSelector("#myId");
browser.close();

to call launch to launch the browser.

We call awaitForSelector to wait for the element with ID myId to show.
