what do you know about YANG?

You may know JSON and YAML and how they are sometimes used to write app configurations. But when it comes to networking devices we have something similar called YANG (Yet Another Next Generation). In the battle of config formats, JSON and YAML are vibing at the afterparty— YANG’s out here managing the entire venue. If you've ever fiddled with networking devices, and configuration protocols, or just wondered how big telecom giants manage to speak a common language across millions of devices—say hello to YANG. YANG (Yet Another Next Generation) is a data modeling language, primarily used to model configuration and state data manipulated by the NETCONF protocol. Think of YANG as the JSON Schema of networking but with extra swagger and stricter formalism. It’s not some fringe tech; it’s the backbone of modern network automation, powering SDN (Software-Defined Networking), cloud infra, IoT setups, and any scenario where zillions of networking devices need to stay sane and synced
