Specify for the V type parameter a constraint that is a union of two
types: int64 and float64. Using | specifies a union of the two
types, meaning that this constraint allows either type. Either type
will be permitted by the compiler as an argument in the calling code.

Tutorial: Getting started with generics - The Go Programming Languagees that map keys be comparable. So declaring K as comparable is necessary so you can use K as the key in the map variable. It also ensures that calling code uses an allowable type for map keys. <span>Specify for the V type parameter a constraint that is a union of two types: int64 and float64. Using | specifies a union of the two types, meaning that this constraint allows either type. Either type will be permitted by the compiler as an argument in the calling code. Specify that the m argument is of type map[K]V, where K and V are the types already specified for the type parameters. Note that we know map[K]V is a valid map type because K is a compa Summary
