metatables

what is the advantage of metatables? i've been coding for 8 months now, i've seen several examples of setmetatable here and there, still couldn't figure out what it does/how does it work. any comment is appreciated

well yeah, of course i checked it out. i kind of understand what metatables do but the thing i am having a trouble with is what is metatables' advantage. i mean, can i still do the same things as metatables do without having to use metatables?
