Welcome to this new series/course! The goal of this series is that we’re going to take a simple VueJS project and upgrade it to use Typescript! You may wonder, “why to use typescript in my VueJS project if I’m fine with the good old fashioned way?” The answer is simple. There are sometimes that our project can get bigger than we expected and creating new features or a simple refactor could scare us. This is because, most of the time, we don’t have any idea if something else gets broken or how many files need to change to put our feature/refactor in place.
