COVER // HOW WOULD YOU DESIGN AN EXPRESS.JS APPLICATION THAT EFFICIENTLY HANDLES A LARGE NUMBER OF CONCURRENT DATABASE CONNECTIONS, AND WHAT STRATEGIES WOULD YOU EMPLOY TO MANAGE POTENTIAL BOTTLENECKS?

To handle a large number of concurrent database connections in an Express.js application, I would use a connection pooling strategy in combination with an ORM or query builder. This allows for reusing existing connections and minimizes the overhead of establishing new ones, thus improving performance while monitoring and tuning database queries to avoid bottlenecks.
