Untyped maps (AnyMap / object)

An untyped map represents a JSON-like structure with a value that can either be a number, a string, a boolean, a bigint, a null, an array or an object.

TypeScript

interface Fetch extends HybridObject {
  get(url: string): AnyMap
}

C++

class HybridFetch: public HybridFetchSpec {
  std::shared_ptr<AnyMap> get(const std::string& url);
}

Swift

class HybridFetch: HybridFetchSpec {
  func get(url: String) -> AnyMapHolder
}

Kotlin

class HybridFetch: HybridFetchSpec() {
  fun get(url: String): AnyMap
}

tip

While untyped maps are implemented efficiently, Nitro cannot sufficiently optimize the object as keys and value-types are not known in advance. If possible, avoid untyped maps and use strongly typed objects instead.
