Worked on the fastly/js-compute-runtime repository to enhance the Dynamic Backends Documentation, focusing on clarifying how services define backends and explaining the automatic creation of backends when the 'backend' option is omitted in fetch requests. This update, implemented using Markdown and documentation best practices, aimed to improve developer understanding and reduce potential misconfigurations related to dynamic backend configuration. The work aligned the documentation more closely with actual runtime behavior, supporting better onboarding and future extensibility. No major bugs were addressed during this period, as the engineering effort concentrated on refining documentation quality and providing clearer guidance for developers using js-compute-runtime.
