I've been writing JavaScript since before it was cool. Before React, before Node, before anyone thought you could build real software with it. Twenty-five years of shipping code — agencies, startups, enterprise, the whole spectrum.

This blog is where I share what actually works.

What You'll Get Here

Short posts. Working code. Opinions.

I'm not here to explain what a variable is. I'm here to show you the fundamentals that create real unlocks — the kind of knowledge that makes everything else click. Think less "tutorial" and more "conversation with a senior dev who's seen some things."

Every post earns its place. If I can't say it in 500 words, it's probably two posts. Your time matters.

What I Believe

Fundamentals beat hacks. Quick tricks get you through today. Understanding gets you through your career. I'll always choose the lesson that compounds.

Code speaks louder than paragraphs. You'll see a lot of code blocks here. That's the point.

Empowerment over information. I want you to leave each post feeling more capable, not just more informed. That's the difference between reading and learning.

What's Coming

I'll be covering the JavaScript and TypeScript ecosystem — frameworks, tooling, AI integrations, developer productivity. The stuff I actually use to build products.

Some posts will be tactical: here's a problem, here's the fix, ship it. Others will be perspective: here's how I think about this, take what's useful.

All of it comes from building real things, not just reading docs.

One More Thing

I'm not a persona. I'm a real developer — John Ryan Cottam, if you want to look me up. JavaScript Johnny is just the voice. Direct, maybe a little opinionated, always trying to help you level up.

If that sounds useful, stick around.

Let's build something.
