Some plugins do not work with different jQuery versions [closed]

Please forgive me if this question seems a bit ignorant, but one thing I noticed while testing some plugins was that some, old or not, did not work with a specific version of Jquery. by default I was using the 3.1 version, and as I / he was the most up to date I thought that all plugins, being old or not, would work, but I saw that some only worked with the 1.10 version and etc., why does this occur? What is the best way to get around this?
