Connecting a JavaScript Web Application to a C++ Backend

I have a c++ program that is running on RPi and want to add a web interface to change parameters in c++ program.

If I am going to use javascript, what would be the easiest way to do this? I am totally new to javascript, no idea what sort of tools and libraries are there.

I found a couple of articles but many of them are almost 10 years old. So, I am not sure which one is the current trend and the way to go.

The application running on RPi is taking the video(1~10fps) from RPi camera and does some image processing. So, the web interface should be able to show the video and send control parameters(camera control, image processing parameters) to the backend program as well.
