react with ci or laravel

[leo037]

I have been using CI and jquery to build web applications for past few years and I am very comfortable using it.
Now, I am planning to start new project using reactjs or angular or vue on the frontend.

Laravel is completely new for me and I think it'll take some time getting used to like CI. There are some good features that I liked but also, I think learning two languages Laravel or whichever JS language I choose at once is going be a bit tough.

So, would it better to learn Laravel or continue using Codeigniter?
I have already built lots of functions and libraries for CI.

Also, what I like about CI is it's stable versions. The changes are slow and minor. So, I don't have to make lots of changes in codes even when I want to upgrade.
Laravel seems to be always changing and upgrading would be hard. While studying tutorials, some v5.4 functions were different than in v5.7.
So, basically if I started laravel project with current version, I think it would be really hard to upgrade to new one when available but for CI, I updated from 2 to 3 with very little problems.

Thank you and hope to get some suggestions.
