I have a headache this evening. Why?
After all, it's just half the way out. My Understanding of javascript only stays at: calling javascript, changing page styles, elements, and implementing responses to some events. Although it may be used when necessary, but the principle of use is not very clear, as for DOM, such a professional word, it is easy to save.
However, one night

1. The relationship between the socket and the process: the socket is used to exchange information (IPC) between a process and other processes, and the socket interface is the API
written at the capture event. This makes code easy to write and maintain, with no complex object-oriented framework, no interfaces, and no over-design possibilities. Just listen to the event, write a callback function, and everything else can be handed to the system for processing!Sample Node ApplicationFinally, let's look at some code! Let's summarize everything we've discussed to create our first Node application. We already know that Node is ideal
of TCP/IP stack operations, rather than a simple ing relationship!

Yesterday, I chatted with my friends about network programming. For socket, here is my personal understanding :)
You can create a socket in a program, which can be divided into two types: Common socket and original socket.
I. Common socket is a programming i
Preliminary knowledge:What is the process? Here's an excerpt from the WIN32 API guide:"A process is an executing application that includes private virtual address space, code, data, and other operating system resources, such as pipelines, files, and synchronization objects that the process can access." ”As you can see from the definition above, a process has seve
