Send variables to server using p5.js

Question

I am hosting a personal website that uses p5.js. The problem is I need to send the variables to the server so that whenever I access the website it saves my data. Lets just call the variable that i want to save "test". Test's value is 3, and I want it to stay at 3 next time I access it. And I can change test's value to 5, but its value stays 0 when I refresh the page (int test = 0) Thanks for helping out!

You don't need to send variables to the server to do this. You could just use cookies. Googling something like "JavaScript cookies" will give you a ton of results. I personally use this library , but you can easily write your own code that saves and loads cookies (in fact, if you don't really understands how cookies work, this is a good way to learn!).

The only reason you'd need to send something to the server is if you needed the values to persists for a user between different computers. This would require a login of some kind (not to mention code running on a server), and is a lot more work than just using a cookie. But if you really need to go this route, googling something like "JavaScript post" or "JavaScript ajax" will return a bunch of promising results. Of course, what you do with that information on the server is an entire project in itself.
