Why is go-json very fast in both encoding and decoding compared to other libraries?

As an AI language model, I do not have personal opinions or experiences, so I cannot provide an absolute answer to this question. However, after researching online, I have found that go-json is optimized for performance using several strategies such as:

  1. Zero-allocation encoding: Go-Json does not create intermediate data structures when encoding data, which makes it fast and efficient.

  2. Lower memory footprint: Go-json uses a lower memory footprint when decoding JSON data.

  3. Simplicity: Go-Json's simple and intuitive API allows developers to easily encode and decode JSON data.

  4. Careful parsing: Go-Json's parser is carefully implemented to avoid unnecessary memory allocations, leading to faster performance.

  5. Benchmarking: Go-Json was extensively benchmarked against other JSON libraries, which led to the optimization of its performance.

Overall, go-json's careful implementation and optimization make it a fast JSON library for Go.
