Today I've spent some time browsing through Stack Overflow questions - looking for interesting questions that I might take a stab at answering.
An outcome of that effort has been the serendipity of learning about the following...
Puppeteer
"Puppeteer is a Node library which provides a high-level API to control Chrome or Chromium over the DevTools Protocol. Puppeteer runs headless by default, but can be configured to run full (non-headless) Chrome or Chromium."
What can it do?
- Generate screenshots and PDFs of pages.
- Crawl a SPA (Single-Page Application) and generate pre-rendered content (i.e. "SSR" (Server-Side Rendering)).
- Automate form submission, UI testing, keyboard input, etc.
- Create an up-to-date, automated testing environment. Run your tests directly in the latest version of Chrome using the latest JavaScript and browser features.
- Capture a timeline trace of your site to help diagnose performance issues.
- Test Chrome Extensions.
Here are some interesting links:

JS1K - The JavaScript Code Golfing Competition
I perused the code of some of the past competition winners - and was inspired by the level of conciseness and creativity. Note: It appears the competition's last year was 2019.
