How did you choose tools, for example, how did you compare libraries for JSON parsing?

The choice of tools, such as libraries for JSON parsing, was based on several criteria:

• Performance: comparing parsing and serialization speed on real data.
• Compatibility with the project: support for required language versions and frameworks.
• Functionality: support for necessary formats, customization, validation.
• Ease of use and documentation.
• Community activity and developer support.
• License and compliance with project requirements.

For comparison, prototypes were made with different libraries, measuring execution time and memory consumption, and evaluating API convenience. For example, in Go, the standard encoding/json was compared with jsoniter and easyjson.
