New to web development, backend question

[KernelKiller69]

when deploying my website, does the web works like threads in default,
for example, I have a global array variable (my website has low data transfer, so my global variables are not large)
does person A press a button and the array is filling with person A data
meanwhile, person B comes in and presses the same button, does the data collide or it's individual threats like?

Depends a bit of what you are using. In common backend engines and languages, each request is its own instance, so if person A is manipulating a global value of his instance, it does not affect on person b instance.

In any case try to avoid the use of static variables.

That should absolutely not be a consideration ! Either you're doing it right or you're doing it wrong, not 'halfway right' depending on usage.

I think @EkBass is right in saying with common webservers (e.g. Apache) each client request is running in their own thread and you should not worry about it. It would be very strange if one web client suddenly sees data that was entered by another web user somewhere else in the world !
But when in doubt, by all means test it out. It should not be hard to force the situation and see what happens.

Each person's interaction with your website is separate, so if one person is filling up an array with their data, it won't collide with someone else pressing the same button. The data will be separate for each person, so you don't have to worry about conflicts.

It depends totally on the software and architecture you are using. Eg if, as a beginner you have coded a server that listens for connections and spawns a new thread to handle each one (a common example on tutorial web sites) then yes, the threads will share any global variables and “collisions” will follow. If you use an architecture designed for purpose then they will definitely avoid this problem.
In any case using global variables for a thread’s data is terrible design. Don’t do it.

Oh, and if you're into shopify web development, that's awesome. Shopify is a great platform for creating online stores. It's super user-friendly and has lots of cool features. When you're working on Shopify, just remember to focus on making the user experience smooth and easy. That means having clear navigation, buttons, and layouts that work well on different devices. Also, make sure your website loads quickly because nobody likes waiting around for a slow site.
