Despite the time it was born (2009years) is not long, but it has formed a huge ecosystem around it. node. JS has a strong a
queues and stacks, as one of the simplest and most basic data structures, can be said to be widely used in many aspects. When the program runs, they can save information about the points in the program's run path for backtracking operations or other operations that require access to the node information that has already been accessed. Here the characteristics of the stack, the role of the description, and simply different ways to achieve the basic fun

By using non-blocking, event-driven I/O operations, node. JS provides a great platform for building and running large-scale network applications and services, and is also widely welcomed. Its main features are the ability to handle large, high-throughput concurrent connections to build high-performance, highly scalable Internet applications. However, node.
(which can be understood as the main thread). As for why, you can take a look at the section of the previous event polling, each callback function in Nodejs is called by an event poll in the main thread. This ensures that in Nodejs, any code written by the developer is run in the same thread (so-called single-threaded).
