Is there a foreach construct in the Go language? Can I iterate over a slice or array using a for?

Chris Gregori · Answer

https://golang.org/ref/spec#For_range A "for" statement with a "range" clause iterates through all entries of an array, slice, string or map, or values received on a channel. For each entry it assigns iteration values to corresponding iteration variables and then executes the block. As an example: for index, element := range someSlice { // index is the index where we are // element is the element from someSlice for where we are } If you don't care about the index, you can use _: for _, element := range someSlice { // element is the element from someSlice for where we are } The underscore, _, is the blank identifier, an anonymous placeholder.
