General form of variable declaration in Go is: var name type = expression the above declaration creates a variable of a particular type, attaches a name to it, and sets its initial value. Both create an array of strings, but the difference is in how it is called. func f(args string) { } // Would be called like this: f("foo","bar","baz"); This allows you to accept a variable number of arguments (all of the same type) A great example of this is fmt.Print and friends, which can accept as few or as many arugments as you want.
