Fast and lightweight library for lazy operations with iterable objects.

export declare function first<T, R, N>(iterator: Iterator<T, R, N>, predicate?: (value: T, index: number) => boolean): T | undefined;
export declare function firstAsync<T, R, N>(iterator: AsyncIterator<T, R, N>, predicate?: (value: T, index: number) => boolean | Promise<boolean>): Promise<T | undefined>;
