In plain English

This repository is the companion code library for a Complete JavaScript course hosted on Udemy. It contains starter files, skeleton code to begin each lesson with, and final completed versions of every section and project, exactly matching what is shown in the course videos. The purpose is practical: when you get stuck following along, you can compare your code against the finished version to spot where things went wrong. There is also a separate branch kept up to date with the latest package updates and bug fixes. The course covers JavaScript from the ground up through to advanced topics, with several hands-on projects built along the way, including games, a banking app interface, a geolocation-based map app, and a recipe application. These are real, deployed web projects you can view live and add to your portfolio after completing the course. This repository is not a standalone learning resource, it only makes sense if you are enrolled in the associated Udemy course. If you are taking that course, this is where you download the files you need for each lesson. The code is in JavaScript and is intended for beginners learning web development who want structured, project-based practice.
