I'm thinking of taking the Javascript for WP course

I enjoy using WordPress and have experience with it. also am learning Javascript and want to continue on that track. So I thought Zac Gordon’s JavaScript for WP course would be good for me.

I know the market for JavaScript is much better than the market for WordPress. But taking this course will teach me about the REST API as well as React. My only concern is will taking this tie me to WordPress. Any help would be greatly appreciated. Thanks
