Overview

What is JSONStream?

JSONStream allows developers to parse and generate JSON in a streaming fashion, enabling more efficient handling of large or continuous data streams. This is particularly useful in scenarios where full buffering is impractical due to memory constraints or real-time requirements.

Key differentiator

JSONStream stands out by providing a lightweight, efficient way to handle large or continuous JSON streams without the need for full buffering, making it ideal for memory-constrained environments and real-time applications.
