Why I still love writing vanilla JavaScript

November 1, 2025

There's something deeply satisfying about writing plain JavaScript — no build tools, no dependencies, just a <script> tag and an idea.

In an age of complex frameworks and bundlers, it feels refreshing to open a blank file and start typing logic that runs everywhere. Vanilla JS reminds me why I started coding in the first place: to make things move, react, and feel alive on a screen.

When you work without abstractions, you're forced to really understand what's happening — the DOM, events, timing, scope. Every click handler or API call becomes a direct conversation with the browser. It sharpens your intuition for how the web actually works.

Here's a simple example I always come back to — no React, no frameworks, just JavaScript doing what it does best:

const button = document.querySelector('#btn');
const counter = document.querySelector('#count');

let count = 0;

button.addEventListener('click', () => {
  count++;
  counter.textContent = `Clicked ${count} times`;
});

No setup, no imports — just open your browser and it works.

Why it's still matters

  • Speed: Nothing loads faster than code without dependencies.
  • Control: You know exactly what's happening under the hood.
  • Learning: Every line teaches you something about the browser.
  • Freedom: No need to wait for library updates or deal with breaking changes.

Frameworks are amazing, but they often blur the line between how and why. Vanilla JavaScript keeps that line visible.

It's simple, lightweight, and endlessly capable.

Sometimes, I think the best way to level up as a developer is to go back to the basics — and write a few hundred lines of pure JavaScript, just for the joy of it.
