utatti/previewable-iterator

Previewable-iterator is a TypeScript/JavaScript library that provides a PreviewableIterable class, which extends the standard IterableIterator to include a `preview()` method. This allows developers to peek at the next value in an iterator without advancing it, making it useful for scenarios where lookahead is needed, such as parsing or stream processing. It's designed for JavaScript/TypeScript developers who work with iterators and need more control over iteration flow.
