What is an example of bridging?

Could you please elaborate on bridging? As I understand from the paragraph, it seems to be a crucial concept in the realm of cryptocurrencies and finance, yet its intricacies are not fully grasped by me. Could you provide a concrete example to illustrate the idea of bridging? I'm particularly interested in how it facilitates the interconnection of different blockchain networks and enables cross-chain transactions. Would you also explain the role of bridging in enhancing the interoperability and scalability of the cryptocurrency ecosystem? Thank you for your assistance in clarifying this topic.
