Collections

Targo gives you two collection styles:

• Go-native collections such as slice<T>, map<K, V>, Fixed<T, N>, and chan<T>
• runtime-backed collections such as Array<T>

Choose first, then code

Prefer slice<T> when

• you are writing core logic
• you want Go-native semantics
• you care about low-overhead Go interop

Prefer Array<T> when

• you explicitly want push, map, filter, or reduce
• you are preserving a JS-style collection workflow on purpose

Remember

• map<K, V> is the Targo map type, not JS Map
• chan<T> is a Go concurrency channel, not a Promise abstraction
