So i very recently learned the for i,v in pairs loop and ive seen some people doing "for i,v in ipairs" instead of "for i,v in pairs"? What's the difference?

So basically for i,v in pairs will go through an entire table, and do whatever it's asked to. But for i,v in ipairs has a twist. It stops when it reaches a nil value. For example:

local myTable = {1,2,nil,3}
for i,v in pairs(myTable) do
    print(v)
end

This would output:

1
2
3

But if we did:

local myTable = {1,2,nil,3}
for i,v in ipairs(myTable) do
    print(v)
end

Would only output:

1
2

Because it stops at the nil value
