Does the standard library (or a popular agreed-upon library) let me map, filter, fold etc. over slices/maps?

Although Golang supports functional programming, it wasn't designed for this purpose, as evidenced by the lack of functions like Map, Filter, and Reduce. Functional programming improves the readability of your code because functions are pure and, therefore, easy to understand.
Go (or “Golang”) is a post-OOP programming language that borrows its structure (packages, types, functions) from the Algol/Pascal/Modula language family. Nevertheless, in Go, object-oriented patterns are still useful for structuring a program in a clear and understandable way.
Golang make() is a built-in slice function used to create a slice. The make() function takes three arguments: type, length, and capacity, and returns the slice. To create dynamically sized arrays, use the make() function. The make() function allocates a zeroed array and returns a slice that refers to that array.
No. Go's type system doesn't cater for the usual form of these primitives because it lacks generics.
