This article explains the programming idiom “push ifs up and fors down,” which recommends moving conditional logic to higher levels of control flow and placing loops inside lower-level batch functions. It also connects the idea to database optimization, where filters and projections are applied early and expensive joins are deferred until later, while noting the principle’s broader but not universal applicability.
