How to keep browser open with Selenium WebDriver 4 and JavaScript

Question

How do I keep the browser open with Selenium WebDriver 4, JavaScript, and chromedriver?

With the following code, the browser automatically closes after a few seconds:

require("chromedriver");
const { Builder, Browser } = require("selenium-webdriver");
const driver = new Builder().forBrowser(Browser.CHROME).build();

start();

async function start() {
  await driver.get("https://www.selenium.dev/selenium/web/web-form.html");
}

I know I need to set some options, but the Selenium WebDriver documentation doesn't have a clear example to keep the browser open.
