Difference Between Three.js and Babylon.js: What Actually Should You Choose?


You don’t have to be just a graphic designer to create interactive designs. You can be a coder and still create visually appealing and eye-catching games. All thanks to JavaScript.

The first cross-browser JavaScript library–three.js–that can create 3D computer graphics was first released on 24 April 2010 by Ricardo Cabello. He first wrote the code in ActionScript language, which was then used by Adobe Flash.

But then in 2009, he ported the code to JavaScript. Previously, people used WebGL. But the problem was its limitation: it can create only simple pointers and lines.

Ricardo, instead of abandoning WebGL as something that is futile, used it to his own advantage. He built three.js on top of WebGL. This renders three.js to create 3D graphics in the browser. Even a 3D scene can be created easily using Canvas and WebGL now.

But then in 2013, Babylon.js was created. But why? Why did its creators, Microsoft and David Catuhe, make something that another JavaScript library–three.js –was already doing? Well, that’s because Babylon.js can not only render photorealistic images. It can also create interactive games like Temple Run. To show gadgeteer how HoloLens would look like, Microsoft uses Babylon.js.

But what actually is the difference between Babylon.js and three.js? Well, I’ll tell you here. The first difference between Babylon.js and three.js is that Babylon.js is a real-time 3D engine where 3D graphics are displayed after using HTML5. On the contrary, three.js is a JavaScript library as well as an API that’s used to make and display animated 3D graphics in a web browser.

And since both Babylon.js and three.js are open source, their source code is available on GitHub. Further, the source code of Babylon.js is TypeScript-based and is further compiled into JavaScript. On the contrary, three.js programming languages are JavaScript, OpenGL, and Shading Language.

Babylon.js is already a web rendering engine as per their official websites. But is three.js also a rendering engine? Well, yes, it has 2 official engines — CSS and WebGL. Using Babylon.js one can add visual effects as well. But when it comes to three.js, you can’t add visual effects. You can add a bit of visual effects only after post-processing. Babylon.js runs on Internet Explorer 11+, Firefox 4+, Google Chrome 9+, and Opera 15+ with WebGL support. Three.js, on the contrary, runs on browsers that are supported by WebGL 1.0.

For your ease, I have created a table that highlights the difference between both three.js and Babylon.js.

But What is Worth Learning in Babylon.js and Three.js in 2025?

Well, there isn’t a straight answer to this. If you are new to 3D programming, then you should learn three.js in 2025. That’s because three.js has a clean architecture. Even classes are of simple design. There are also some ready-to-use components in three.js. You can see how many people are downloading three.js here.

But if you already have a good knowledge of graphics and programming, prefer to learn Babylon.js in 2025. But then be ready to handle some mental breakdowns. Babylon.js is harder. But it does have thorough documentation that is better than three.js.

Exploring Google’s New Gemini CLI: The Ultimate Open-Source Dev Tool

  Google quietly released a local AI agent that builds apps, debugs code, parses your repo, and fetches real-time data, right inside your terminal. And it’s completely free. This year, the most revolutionary developer tools I’ve used didn’t come with a splashy launch or billion-dollar hype. It came as a simple CLI: Gemini CLI, a terminal-based AI agent built on top of Google’s Gemini 2.5 Pro model . At first glance, it looks like a lightweight alternative to Claude Code. But after just 10 minutes of use, it became clear: this isn’t just a convenient utility. It’s a powerful local AI development assistant that can analyze, automate, and accelerate almost every part of your software workflow. And best of all? It’s fully open-source under the Apache 2.0 license It gives you up to 1,000 free requests per day It integrates with your local filesystem, IDE, and the web And it runs entirely in your terminal , no browser needed In this guide, I’ll show you what Gemini CLI is, how it works...

Top 25 JavaScript Array Methods Every Developer Should Learn

  You wrote some code. You ran it. And then your array went from a list of users to an angry collection of undefined , NaN And more bugs than a summer camping trip. Staring at map , filter , and reduce like they were ancient scrolls written in Elvish. Copy-pasting from Stack Overflow like a caffeinated zombie. Wondering why the heck splice just murdered half my data. But here’s the truth: mastering arrays is non-negotiable. If you’re fumbling with arrays, you’re fumbling with everything . Web apps, APIs, UIs — they all depend on your ability to tame this glorious beast. So buckle up. I’m about to drop 25 methods that will make you look at arrays like a surgeon looks at a scalpel. Edited by me 1. map() - Because Loops Are for Cavemen You want to transform every item in an array? Don’t go forEach your way to hell. map It is concise, expressive, and doesn’t mutate your data. It’s like therapy for arrays. const names = [ 'alice' , 'bob' , 'charlie' ]; const u...

6 Essential JavaScript Concepts Every Developer Should Understand

It’s the only language I’ve used where [] == ![] it's true and where you can, typeof null and somehow get 'object' . But despite all its quirks (and there are many), there are a few core concepts that make life with JS not just easier, but saner. This isn’t some computer science flex. These are practical concepts that, once you understand them, make you write better, cleaner, and less buggy code. 1. Hoisting  Before you rage at your variables being undefined , understand this: JS hoists variable and function declarations to the top of their scope. But —  and this is important  —  only the declarations , not the assignments. Why? Because JS reads it like: This is also why let and const behave differently — they’re hoisted too, but live in the “Temporal Dead Zone” until declared. 2. Closures Closures are like little memory vaults for your functions. They allow functions to remember variables from the scope they were created in, even after that scope has gone. Why care? T...
