Machine learning always seemed distant from frontend — Python, powerful servers, expensive GPUs. But that changed. Today it's possible to run a trained AI model directly in the browser, with zero backend, using pure JavaScript and the user's own GPU.

This article explains how this works in practice, using TensorFlow.js as a foundation — and how I applied it in a project called SeeFood, a classifier that solves humanity's greatest problem: knowing whether what you're about to eat is a hot dog or not.

Anyone who has spent hours chasing an undefined in the middle of a bundle or a strange behavior only in production knows how an unresolved import chain can become a headache. One of the frequent culprits is the circular import: module A imports B, B imports C, and somewhere in the chain someone imports A again — closing a cycle.

It's wonderful — the build works, the project runs locally, but when you try to deploy, it breaks! \o/

I've seen this in small projects and in large ones; the only difference is the size of the problem you'll face. You can spot the headache with Madge and it's a lifesaver!

To lock up TypeScript, a circular import is a treat.

Many JavaScript developers make a common mistake: doing mathematical calculations directly with the language's native operations. This can cause serious precision problems, especially in financial or scientific applications.

• Explicit Resource Management
• Change Array by Copy Methods
• Hashbang Grammar
• Symbol.prototype.description
• Array and TypedArray findLast and findLastIndex
• Underscored Numeric Separators
• Function.prototype.toString revision
• Top-level await
• WeakRef and FinalizationRegistry

In this article, I will present some good programming practices in JavaScript. However, these practices can be applied to any programming language, as they represent a set of recommended guidelines.

The central concept addressed here is "Clean Code," which refers to code that is easy to read and understand, as well as easy to maintain. The goal is to create clear and concise code.

Before proceeding, I would like to start with a quote from Bjarne Stroustrup, the creator of the C++ language:

"I like my code to be elegant and efficient. The logic should be straightforward to make it hard for bugs to hide, the dependencies minimal to ease maintenance, error handling complete according to an articulated strategy, and performance close to optimal so as not to tempt people to make the code messy with unprincipled optimizations. Clean code does one thing well."

Bun!​

Have you heard of Bun?

Bun is a new JavaScript runtime developed to be a drop-in replacement for Node.js. It natively implements hundreds of Node.js and Web APIs, including fs, path, Buffer, and much more.
