In a for loop, you often have a variable called i.
Example:
local table={"Hi", "there", "everyone!"}
for i=1,#table do
print(table[i])
end
In the for loop, you have a variable called i. It is a counter that is incremented every time the for loop runs until i is greater than #table, which is the number of variables in table.
You use [i] to reference the ith member in table.
To add to chararray256's answer:
[i] on it's own doesn't mean anything, but square brackets are syntactical for indexing tables, i.e. accessing elements of the table that are stored with certain keys.
Take for example this code:
myTable = {"Hello", 7, Instance.new("Part")}
print(myTable[1])
print(myTable[2])
print(myTable[3])
The output would read:
Hello
7
Part
Keys don't have to be numbers though, they can be strings as well!
