Node-js behind the scene [Arabic]

learning basics of node-js is greate but  learning node internal structure and mastering event loop is much more better.

what we will cover ?

1. Node Internal structure :

   • Life cycle on nodejs

   • C++ side of nodejs

   • Binding between c++ and js inside nodejs

2. Master Event Loop:

   • what's event loop tick ?

   • when event loop is start working?

   • we will implement event loop to understand loop behavior instead of diagrams.

3. Is node a single thread?

   • verify to your interviewer that node is't a single threaded by writing code and benchmark it.

4. Libuv Delegation:

   • what's is the purpose of libuv?.

   • how libuv increase nodejs performance?.

   • increasing libuv thread pool size and benchmark our code.

   • thread pool with multi threading.

5. OS Delegation:

   • what's os Delegation?

   • when node and libuv decide to delegate this function to OS?

6. Complex Nodejs Interview Question

   • you will be trained how to solve complex problem and how your threads is distributed among your machine cores

7. What's event loop blocking?

   • we will write code to block our event loop and measure how this blocking impact our performance.

   • we will learn how clustering and worker thread will help us to decrease the impact of the blocking.

8. What 's Node cluster Mode ?

   • we will learn how to run our program in cluster mode.

   • we will use pm2 for cluster managing.

   • How cluster mode solve our event loop blocking?.

9. what's worker threads ?

   • we will learn how to use worker thread.

   • How worker thread solve our event loop blocking?.
