If You Want to Feel Like a Web Wizard

🧙🏻‍♂️ Warning: After this, your browser will feel like a magic wand.

You’ve been learning JavaScript. Maybe writing some functions, building small apps, following tutorials… that’s great.

But what if I told you that JavaScript can be way more fun and useful, even in your browser console?

Let me show you 10 real scripts that you can copy, paste, and run right now — no setup, no frameworks, just instant results.

Bonus: You’ll find tons more cool stuff like this on javascript.0x3d.site—it’s your new playground.

1. Download Every Image on a Page

Tired of right-clicking one by one?

[...document.images].forEach((img, i) => {
  fetch(img.src)
    .then(res => res.blob())
    .then(blob => {
      const a = document.createElement('a');
      a.href = URL.createObjectURL(blob);
      a.download = `image-${i}.jpg`;
      a.click();
    });
});
Enter fullscreen mode Exit fullscreen mode

🖼️ Boom—your gallery’s yours now.

2. Turn Any Page Into a Rainbow Disco

Perfect for annoying your coworkers or freaking out your friends.

setInterval(() => {
  document.body.style.backgroundColor =
    `hsl(${Math.floor(Math.random() * 360)}, 100%, 50%)`;
}, 100);
Enter fullscreen mode Exit fullscreen mode

🌈 Please use responsibly.

3. Find All Password Fields and Reveal Them

Because sometimes… you are the hacker.

[...document.querySelectorAll('input[type="password"]')]
  .forEach(input => input.type = 'text');
Enter fullscreen mode Exit fullscreen mode

👀 Oops, did I just expose all passwords?

4. Make All Text on a Page Editable

Yup. Like a mini Notion clone.

document.body.contentEditable = true;
document.designMode = 'on';
Enter fullscreen mode Exit fullscreen mode

📝 Go ahead—edit headlines, rewrite articles, prank your friend’s LinkedIn.

5. Play a Sound Without Any Library

Want to blast a beep just because?

new Audio('https://actions.google.com/sounds/v1/cartoon/cartoon_boing.ogg').play();
Enter fullscreen mode Exit fullscreen mode

🔊 You can trigger sounds on clicks, keypresses, or chaos.

6. Auto Scroll a Page Like It’s Reading to You

Just sit back and relax.

setInterval(() => {
  window.scrollBy(0, 5);
}, 50);
Enter fullscreen mode Exit fullscreen mode

📖 Feels like magic when paired with speech synthesis.

7. Convert Any Page’s Text into Speech

Okay, this one’s genuinely useful.

const msg = new SpeechSynthesisUtterance(document.body.innerText.slice(0, 500));
speechSynthesis.speak(msg);
Enter fullscreen mode Exit fullscreen mode

🗣️ The web… talks back now.

8. Highlight All Links That Go to External Sites

Click smart.

[...document.links].forEach(link => {
  if (!link.href.includes(location.hostname)) {
    link.style.backgroundColor = 'yellow';
  }
});
Enter fullscreen mode Exit fullscreen mode

⚠️ This is great for SEO, audits, or nosy curiosity.

9. Show How Many Words Are on a Page

Because who has time to count?

alert(document.body.innerText.trim().split(/\s+/).length + ' words on this page.');
Enter fullscreen mode Exit fullscreen mode

✍️ Use it on blogs, articles, or to guilt-trip yourself on Reddit.

10. Print a Clean Screenshot of Any Page Without Ads

Remove all the clutter first:

[...document.querySelectorAll('header, footer, nav, aside, .ad, [class*="ad"]')].forEach(el => el.remove());
window.print();
Enter fullscreen mode Exit fullscreen mode

🖨️ Welcome to print-friendly mode, the chaos edition.
