setTimeouts inside a for loop

So I've encountered a problem that I've been trying to solve for a week now... Say I have a setTimeout inside a for loop. Inside the setTimeout function I have -> setTimeout(callback, timer, parameters of the callback). My problem is that, the values of the parameters aren't always the values that I am expecting and it seems to be that their values are always getting overwritten on each execution. My question is, how can I avoid this in a way where the values of the parameters aren't overwritten. I know this has something to do with scope but I'm not too sure how to approach it or do it.
