Just like in the Go programming language, Go and Hugo templates make heavy use of `range` to iterate over a map, array or slice. Other templating languages use a foreach for the equivalent functionality.

`range` is fundamental to templating in Hugo. (See the [Introduction to Hugo Templates](/templates/introduction/) for more examples.)
