Generics

Allows a function to receive type parameters

func sumSlice[T int | float32 | float64](slice []T) {
	var sum T
	for _, v := range slice {
		sum += v
	}
	return sum
}

We can also use the any type to allow a function to take in any type
- func bar[T any] {...}
Can also be used with structs

type car [T gasEngine | electricEngine] struct {...}
