To optimize performance with a high read/write ratio, implementing caching mechanisms is a common strategy. Options 2, 3, and 4 are not recommended for this purpose. "findOneAndUpdate" is not related to optimizing read/write efficiency. Disabling indexing can harm performance, and increasing the connection pool size alone won't optimize database interactions.

To optimize CRUD operations, caching strategies like write-behind caching can be effective, where data is cached and written back to the database asynchronously. Caching reduces the need to access the database for every write operation, improving performance.

The npm update command can be used to update the package.json file to match the actual versions installed in the node_modules directory. This command will update the version numbers of packages in package.json based on the versions currently installed.

To ensure fast and accurate search functionality in a large-scale e-commerce platform, employing Inverted Indexes and Distributed Search Engines is a common strategy. These technologies allow for efficient and scalable search operations, as they pre-process and index the data in a way that speeds up retrieval. Full-Text Search Indexing is useful for searching within product descriptions. In-memory caching can further enhance query performance by storing frequently accessed data in memory. However, it's not a substitute for proper indexing and search strategies.

Pug was previously known as "Jade" before it was renamed due to a trademark issue. The other options are different templating engines and not related to Pug.

When destructuring properties not present in the object, they will be assigned undefined, and no error will be thrown. This is useful for handling optional properties or providing default values.

To avoid blocking the Event Loop with CPU-bound tasks, Node.js developers can offload such tasks to "Worker Threads." This allows for concurrent execution of tasks, ensuring that the Event Loop remains responsive for handling other I/O operations and events.

The Buffer.isBuffer method is used to determine if an object is a buffer in Node.js. It helps identify whether a given object is a Buffer instance or not.

To optimize write-intensive workloads in a database, it's crucial to minimize the use of "Locks." Locks can lead to contention and slow down write operations, especially in scenarios with high concurrent writes.

To access the properties of an object in JavaScript, you use dot notation like object.property. This is the most common and straightforward way to access object properties. The other options are not standard ways to access object properties.

When designing a schema for real-time analytics, indexing relevant columns is crucial as it speeds up data retrieval. Option (2) is also valid, as caching can significantly reduce database load. Option (3) might be a consideration but isn't the primary factor. Option (4) can be a trade-off, and it depends on the specific use case.

process.nextTick() is used to schedule a callback function to be executed in the next iteration of the event loop, immediately after the current operation is complete. This allows for efficient asynchronous code execution. The other options do not accurately describe the purpose of process.nextTick().
