This guide will walk you through the standard Git workflow, explaining the most commonly used commands. If you’re new to Git, this guide will help you get up and running in no time! Prerequisites: * Git installed * Passing familiarity with the *nix command line What is Git? Git is a…
Have you ever found yourself saying "but it works on my machine" when your code fails in production? Or spent hours setting up development environments for new team members? Maybe you've struggled with dependency conflicts between different projects? Docker solves these problems by packaging your application…
If you've been using Maps and Sets in your JavaScript applications (if not, check out my previous tutorial), you might have come across their lesser-known cousins: WeakMap and WeakSet. These specialized collection types were also introduced in ES6, but they're often overlooked despite offering unique memory…
