I want to become FullStack dev from Mechanical designer, pls help

I am a full time mechanical designer and want to change my field. I have a good knowledge of html and basic in css. I come to finalize these two courses to go through, but still confused which one should I go with ?

I can afford both courses, but my concern is which course is much better to start with.

1. https://www.udemy.com/course/the-web-developer-bootcamp/ 2. https://www.udemy.com/course/the-complete-web-development-bootcamp/

Any help would be appreciated. I am located in North America, if that makes any difference. I am good with self study. I have learned SolidWorks, Keyshot and many more platform by self learning.
