Building a Perceptron from Scratch in Vanilla JS — No Libraries, Just Math

I just published a Spanish tutorial on building a perceptron from scratch in Vanilla JS, with no libraries. The goal is not just to “use AI”, but to understand the smallest possible neural unit as executable code: inputs → weighted sum → activation → error → weight update If you enjoy low-level explanations and code-first teaching, this one is for you. https://tucodigocotidiano.yarumaltech.com/leer_tutoriales/el-perceptron-desde-cero-escribe-la-matematica-de-una-red-neuronal-simple-en-vanilla-js-sin-librerias/
