I need to surface some information from SPO within SPO page. I am familiar with on-premise CSOM script webparts where I simply added JavaScript and CSOM code.
In SPO, can I still use the same approach (as I can see that new releases of CSOM are available) or will I have to learn something new like SPFX/React ?
I found a blog on the subject of SPFX and seems quite involved.
What is the easiest way to meet my requirements with limited learning involved?
