О чём код?
import Repl from '@/repl/Repl.tsx'; import CodeLink from '@/mdx-components/CodeLink.tsx'; # OrderedSet A type of [`Set`](../Set/) that has the additional guarantee that the iteration order of values will be the order in which they were added. <Signature code={`type OrderedSet<T> extends Set<T>, OrderedCollection<T>`} /> The iteration behavior of OrderedSet is the same as native ES6 Set. Note that `OrderedSet` are more expensive than non-ordered Set and may consume more memory. `OrderedSet#add` is amortized `O(log32 N)`, but not stable. ## Similar API with `Set` `OrderedSet` has the exact same API as [`Set`](../Set/). The only new method is <CodeLink to="isOrderedSet">OrderedSet.isOrderedSet(maybeOrderedSet)</CodeLink> to check if a value is an `OrderedSet`. ## Construction <MemberLabel label="OrderedSet()" /> Create a new immutable OrderedSet containing the values of the provided collection-like. <Signature code={`OrderedSet<T>(collection?: Iterable<T> | ArrayLike<T>): OrderedSet<T>`} /> Note: `OrderedSet` is a factory function and not a class, and does not use the `new` keyword during construction. <Repl defaultValue={`OrderedSet([1, 2, 3])`} /> ## Static Methods <MemberLabel label="OrderedSet.isOrderedSet()" /> True if the provided value is an OrderedSet. <Signature code={`OrderedSet.isOrderedSet(maybeOrderedSet): boolean`} />
