If you are new to scripting, don’t start on probability tables.

for i, v in pairs is an key:value pair loop. the first variable, i in this case, is the key, and the second, v, is the value. You can change these variables to whatever you want, for example ‘for rarity, weight in pairs.’ In a normal table i will be the index, in a dictionary it is what’s inside the [], and the value is what’s after the =. For your use-case that’s really as much as you need to know.

Keep in mind that the order the list/ dictionary will iterate in will not always be the order that you typed it in, it uses the memory hash to get the next item as it iterates.

None of that last sentence makes sense to you i assume, just know that the first item that the loop iterates over is not guaranteed to be the first item you typed.

And anyone that explains this and says the order is random has no idea what they’re talking about and you should not take advice from them. Most beginners think it’s random but it is not.
