I recently started a green field project with sprint boot and Kotlin and it’s a joy compared to the many other things I’ve experienced in the last decade. I’m hoping spring remains strong for a while.
I hate not using it at work but rather Node all the while watching Typescript libraries reinvent the Spring wheel.
Hence when I am not using one, I am doing the other, sometimes with a bit of C++ underneath, unless forced to use another programming stack due to external decisions.
It has worked quite alright for almost 30 years now.
