1 - Node.js event loop: A single threaded, non blocking event loop that handles all asynchronous operations.
2) Cluster vs. Workers: Workers run within a single process while clusters span multiple processes, providing better isolation and fault tolerance.
3) Process Manager vs. Node.js cluster: Process managers (e.g., PM2) provide additional features like auto restart and load balancing, while the Node.js cluster is more lightweight.
4) Streaming: Handling large datasets efficiently by processing data in chunks without loading the entire dataset into memory.
5) HTTP/2 and WebSockets: Improved performance and reduced latency for web applications using HTTP/2 and bi directional communication channels using WebSockets.
6) Async/Await and Promises: Modern asynchronous programming techniques that enable cleaner and more readable code compared to callbacks.
7) Database Optimization: Techniques for optimizing database queries, indexes, and data structures to enhance performance and reduce bottlenecks.
8) Load Balancing and Auto Scaling: Distributing requests across multiple servers to handle traffic peaks and ensure high availability.
9) Security Best Practices: Implementing authentication, authorization, and encryption measures to protect applications from vulnerabilities.
10) Testing and Monitoring: Unit testing, integration testing, and performance monitoring tools to ensure code quality and application health.
11 - Docker and Kubernetes: Containerization and orchestration technologies for deploying and managing Node.js applications in distributed environments.
12) Performance Optimization: Techniques for profiling and optimizing Node.js applications to identify bottlenecks and improve efficiency.
13) Microservices Architecture: Breaking down monoliths into smaller, independent microservices for increased flexibility and scalability.
14) GraphQL: An efficient data query language that allows clients to request specific data from a server without over fetching or under fetching.
15) Event Sourcing: A design pattern that stores a series of immutable events to reproduce the current state of a system and enable event driven architectures.
- Increase your activity level. The more active you are, the more points you'll earn. Try to get at least 30 minutes of moderate intensity exercise most days of the week.
- Complete daily challenges.* Every day, you'll be given a new challenge to complete. These challenges are usually simple and easy to do, and they can earn you a significant number of points.
- Refer your friends.* If you refer your friends to the app, you'll earn points for each person who signs up and becomes active.
- Participate in community events.* The app often hosts community events, such as walks, runs, and races. Participating in these events is a great way to earn points and get active.
- Reach your goals.* When you reach your goals, you'll earn a bonus amount of points. This is a great way to stay motivated and on track.
