Converting JavaScript to TypeScript

Question

Is there a "correct" order to start converting JavaScript to TypeScript? In my case, everything is mostly in Angular so there are a few controllers and services.

What would should be the first step? This is what I currently have:

App.js
Controller1.js ...
Service1.js ..
angular/jQuery.js

More information: I am using VS Code to do this and the project I would like to convert is a SharePoint app.

What would should be the first step? This is what I currently have:

Add a tsconfig.json with allowJs set to true. TypeScript understands JavaScript! Then you will start the change the extensions of the file from .js to .ts one by one.

I did a video on the subject: https://www.youtube.com/watch?v=gmKXXI_ck7w and also created a tool (that you can use in combination with vscode or whatever other IDE you want) to help people like you: http://alm.tools/ 🌹.
