The key can be of any type for which the equality operator is defined,

supports equality). Structs, arrays and slices cannot be used as map keys,
because equality is not defined on those types.

Like slices, maps are a reference type. If you pass a map to a function

in the caller.

They're called <em>goroutines</em> because the existing

function executing in parallel with other goroutines in the same

a prefix naming the package that generated the error. For example, in package
