  • The Prompt Engineering Playbook for Programmers

    Developers are increasingly relying on AI coding assistants to accelerate our daily workflows. These tools can autocomplete functions, suggest bug fixes, and even generate entire modules or MVPs. Yet, as many of us have learned, the quality of the AI’s output depends largely on the quality of the prompt you provide. In other words, prompt engineering has become an essential skill. A poorly phrased

              In this post I’ll walk through the full implementation of a Virtual DOM in a bit over 200 lines of JavaScript. The result is a full-featured and sufficiently performant virtual DOM library (demos). It’s available on NPM as the smvc package. The main goal is to illustrate the fundamental technique behind tools like React. React, Vue and the Elm language all simplify the creation of interactive web

Can a developer's actions, directly or indirectly, impact performance and memory consumption? Let's try to delve i
