Most programming tends to decompose doing an operation for each element in a sequence into implementing the operation for a single element and then doing that repeatedly in a loop. This is obviously wrong for performance reasons, as operations tend to have high latency but multiple of them can run in parallel, so many optimizations are possible if you target bandwidth instead. There are many languages (and libraries) that are array-based though, and which translate somewhat better to how number crunching can be done fast, while still offering pleasant high-level interfaces.
