{loops} is about looping constructs which allow a programmer to apply the same operation multiple times, each time with possibly different parameters.

is about looping constructs which allow a programmer to apply the same operation multiple times, each time with possibly different parameters.

In plain TeX and in LaTeX, one can implement this using counters and `\ifnum` checks or `\loop\unless`. Some LaTeX packages even provide their own looping constructs, e.g. TikZ/PGF provides `\foreach`, pstricks provides `\psforeach`, multido provides `\multido`, etc.
